If we look at angle BOD, that would form a right angle (90°), given that one part of that whole angle is 30°, the other would be;
30° + x = 90°
-30 -30
x = 60°, therefore ∠BOC = 60°.
If we take a look at angle EOC, we can see that that angle is a straight angle (180°), we can also see that a right angle (90°) is a part of that angle alongside the angle we just previously found (60°). So all of those angles plus the unknown angle (AOE) which we will consider 'x' summed up would result in 180 degrees.
Now we set up the equation;
90° + 60° + x = 180°
150 + x = 180
-150 -150
x = 30°, therefore ∠AOE = 30°.
16.
The sum of the interior angles in a triangle will always equal 180°. (We can also confirm this using the formula (n - 2) x 180.)
Given two of the angles, we must add them and the unknown angle(D) which we will consider 'x' to make it result in 180°.
Now we set up the equation;
55° + 18° + x = 180°
73 + x = 180
-73 -73
x = 107°, therefore ∠EDF = 107°.
17.
To find angle P, we must first find the supplement of 34° because 34° and the angle beside forms a straight angle (180°).
Set up an equation;
34 + x = 180
-34 -34
x = 146°, now that we've found the supplement, we add this supplement with the other given angle (23°) because all three angles (unknown angle which we will consider x + 23 + 146) will equal 180°(sum of interior angles of triangle).
146° + 23° + x = 180°
169 + x = 180
-169 -169
x = 11°, therefore ∠QPR = 11°.
18.
Seeing that the bigger triangle has a 90° angle (indicated with a square), and two other equal angles(indicated with the two lines on both legs of the big triangle), we solve for those two missing equal angles in the bigger triangle which we will then use to solve for the smaller triangle's angle.
2x + 90° = 180°
-90 -90
2x = 90
/2 /2
x = 45°, so now we know the two angles in the bigger triangle excluding the right angle.
One of those equal angles is vertical to the smaller triangle, and vertical angles are congruent.
Hence, the angle vertical to the bigger triangle in the smaller triangle will be 45°.
Now we solve for ∠CDE.
Add the two angles and the missing angle to equal 180°.
Set up the equation;
86° + 45° + x = 180°
131 + x = 180
-131 -131
x = 49°, so ∠CDE = 49°.

The measures of the bases of a trapezoid are 14 and 20. What is the measure of the median of the trapezoid?
Answers
The median of the trapezoid is = 17
calculation of the median of a trapezoidA trapezoid is a quadrilateral with one pair of opposite sides parallel. It has parallel sides which are known as the bases.
The base of the trapezoid(B1) =14
The base of the trapezoid (B2) = 20
To calculate the median = half the sum of the base of the trapezoid given.
Therefore,
14+20/2
34/2= 17
Therefore, the median of the trapezoid is = 17

What is the surface area of the triangular prism shown?
A triangular prism. The triangle faces have base 14 meters and height 24 meters. The rectangular bottom has dimensions 10 meters by 14 meters. The height of the prism is 25 meters.
558 m2
976 m2
1,680 m2
1,750 m2
Answers
Answer: 726 meters²
Step-by-step explanation:
We will need to find the area of five shapes. The base, the top/bottom, and the two triangle sides.
The area of a triangle is B * H / 2. Since we have two congruent triangles, I will not be dividing by two.
14 * 24 = 336 meters²
-> This value is for both of the triangle faces
The rectangular bottom is L * W
14 * 10 = 140 meters²
The two rectangles for the top and bottom will also be L * W. Since these are congruent, I will find the area of one and multiply it by two.
10 * 25 = 250 meters²
Now I will add them all together for the total surface area:
336 + 140 + 250 = 726 meters²
-> I don't see this as an option choice listed. I will review my work, but I am currently confused on the options they provide.

A water-walking ball has a volume of approximately 4.19 m 3 . What is the radius, r, of the ball?
Answers
[tex]~~~~~~V = 4.19 \\\\\implies \dfrac{4}3 \pi r^3 = 4.19\\\\\implies r^3 = \dfrac{4.19 \times 3}{4\pi}\\\\\implies r^3 = \dfrac{12.57}{4\pi} \\\\\implies r = \sqrt[3]{\dfrac{12.57}{4\pi}}\\\\\implies r= 1.00009..\\\\\implies r \approx 1~ m[/tex]
The value of radius of water-walking ball is,
⇒ r = 1.003 m
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A water-walking ball has a volume of approximately 4.19 m³.
Since, We know that;
Volume of sphere = 4/3πr³
Hence, We get;
⇒ 4.19 = 4/3 × 3.14 × r³
⇒ r³ = 1.001
⇒ r = 1.003 m
Thus, The value of radius of water-walking ball is,
⇒ r = 1.003 m

if your parents shop in maryland the sales tax is 6% if they buy $180 worth of groceries what is there total
Answers
You can do this problem in two ways.
Either the long way or the short and easy way.
Here is the easy way:
You do 180x1.06 to get you their total of $190.80
Or you can do the slightly longer way which finds you the tax amount which then you can add onto the total:
You do 180*0.06 which gets you $10.80 of tax. $10.80 is how much tax they have to pay on top of the $180, then we can do 180+10.80 to get us the grand total of $190.80.

Answer:

Step-by-step explanation:
https://brainly.com/question/17253194
Speed is the change in distance of a body with respect to time.
Speed = Distance/Time
If the library made a copy of leslie's 3 page essay in just 1/10 of a minute, this means that she made 3 pages in (1/10 * 60)secs i.e 6secs
To get the speed, we need to calculate the amount of page of essay that are produced in a minute (60secs).
If 3 page essay = 6secs
x page essay = 60 secs
cross multiply
3*60 = 6x
180 = 6x
x = 180/6
x = 30
This shows that 30 page essays are produced in just a minute. Hence the speed of the copy machine is 30page essay/min.
