Answer:
x = 70
Step-by-step explanation:
Ok first let's find the angle where there is an exterior angle:
180-120=60
Then add this and the other inside known angle and subtract that from 180 to get your answer:
60+50=110
180-110=70
Answer:
70
Step-by-step explanation:
Sum of two interior angles equals to the exterior angle.

An air traffic controller is monitoring the altitudes of four planes. The four equations below show y, the
distance in feet of each plane above the ground, after 6 minutes of descent. (Hint: Look at the slopes to help
you.)
Plane A: y = 400t + 12,000
Plane B: y = -800t + 28,000
Plane C: y = -200t +13,500
Plane D: y = -500t + 30,000
a. Which plane is descending at the slowest rate?
b. Which plane began its descent from the highest altitude?
Answer:
Step-by-step explanation:
a. Plane C has the slowest rate of descending.
b. Place D has begun to descend from the highest altitude.
What is the equation of a line in slope intercept form?The equation of a line in slope intercept form is y = mx + b where the slope is m and the y-intercept is b.
The altitude of four planes is represented by y after 6 minutes and t represents time in minutes.
To determine which plane is descending at the slowest rate we have to look for a slope in these four equations which is the least steep or which modulus value is the least.
If we take the modulus of all four slopes 200 is the least value.
∴ Plane C has the least descending rate.
To determine which plane starts descending from the highest altitude we look for the value of y-intercept which is the largest among them and that is plane D.

The answer is 95
3x=120 head by head angle
so the x=40
m TVZ also meet the (2x+15) angle
m TVZ = 2x+15
and the x equal to 40
m TVZ= 2(40)+15
m TVZ= 80+15
m TVZ= 95.

" lon works at a restaurant and earns $20 for each shift, plus an hourly wage of $9.50. He earned $58 on his last shift, but forgot how many hours he worked. he was able to solve for his shift length bu subtracting 20 from 58 and then dividing by 9.50. Which of the equations below can be solved with these steps? "
A) 58x - 20x = 9.50
B) 9.50x + 20 = 58
C) 20x + 58x = 9.50
D) 20 = 58 + 9.50x
Answer:
The answer is b
Step-by-step explanation:
x represensts the number of hours worked with 9.50 for every hour and then you add an extra 20 because that's what his job gives him just for showing up

(4,5)
b. What is the equation of line j?
710
m
(5.2)
2-
109
(-3,-1)
a. The equation of line k in slope-intercept form is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)
a) The equation of line k is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
b) The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]
The equation of a line, in slope-intercept formula, is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Line k intersects line m with an angle of 109º, thus:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
In which [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of k and m.
Line k goes through points (-3,-1) and (5,2), thus, it's slope is:[tex]m_1 = \frac{2 - (-1)}{5 - (-3)} = \frac{3}{8}[/tex]
The tangent of 109 degrees is [tex]\tan{109^{\circ}} = -\frac{29}{10}[/tex]Thus, the slope of line m is found solving the following equation:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
[tex]-\frac{29}{10} = \frac{m_2 - \frac{3}{8}}{1 + \frac{3}{8}m_2}[/tex]
[tex]m_2 - \frac{3}{8} = -\frac{29}{10} - \frac{87}{80}m_2[/tex]
[tex]m_2 + \frac{87}{80}m_2 = -\frac{29}{10} + \frac{3}{8}[/tex]
[tex]\frac{167m_2}{80} = \frac{-202}{80}[/tex]
[tex]m_2 = -\frac{202}{167}[/tex]
Thus:
[tex]y = -\frac{202}{167}x + b[/tex]
It goes through point (-2,6), that is, when [tex]x = -2, y = 6[/tex], and this is used to find b.
[tex]y = -\frac{202}{167}x + b[/tex]
[tex]6 = -\frac{202}{167}(-2) + b[/tex]
[tex]b = 6 - \frac{404}{167}[/tex]
[tex]b = \frac{6(167)-404}{167}[/tex]
[tex]b = \frac{598}{167}[/tex]
Thus. the equation of line k, in slope-intercept formula, is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
Item b:
Lines j and k intersect at an angle of 90º, thus they are perpendicular, which means that the multiplication of their slopes is -1.Thus, the slope of line j is:
[tex]-\frac{202}{167}m = -1[/tex]
[tex]m = \frac{167}{202}[/tex]
Then
[tex]y = \frac{167}{202}x + b[/tex]
Also goes through point (-2,6), thus:
[tex]6 = \frac{167}{202}(-2) + b[/tex]
[tex]b = \frac{(2)167 + 202(6)}{202}[/tex]
[tex]b = \frac{1546}{202}[/tex]
The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]

How many square yards of carpet are needed to cover the floor of a related 15 feet long and 12 feet wide
Answer:
20 yards squared.
Step-by-step explanation:
First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.
The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.
