Answer:
[tex]-\frac{8}{x-a}[/tex]
Step-by-step explanation:
[tex]\frac{8}{a-x}[/tex]
we can take common factor of -1 in the denominator
[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]
and now multiply and divide by -1
[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]

Answer:
65 degrees
Step-by-step explanation:
The missing angle on the bottom is 35 degrees. This is because it lies on a straight line with the other angle being 145 degrees and a straight line is always 180 degrees, so 180-145=35 degrees. Now we have to find x so we should add the two known angles (35+80=115) and subtract it from 180 (180-115) to get 65 degrees for x.

Hey there!
For equations like this I usually find the GCF or Factors of the given numbers for both of numbers and factor/solve it from there!
So, I’ll do the same thing for you.

a=5 and c=13 what is the value of b?
Answer: 8 is the answer
Step-by-step explanation:
Answer:
13.928
Step-by-step explanation:
x+y=180
x=10y+48
(With Steps Plz)
Answer:
(168,12)
Step-by-step explanation:
Substitute x = 10y+48 in the first equation.
[tex]10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12[/tex]
We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.
For me, I will be substituting y = 12 in the first equation.
[tex]x + 12 = 180 \\ x = 180 - 12 \\ x = 168[/tex]
Answer Check
Substitute both x-value and y-value in both equations.
[tex]168 + 12 = 180 \\ 180 = 180[/tex]
Our first equation is true for both values.
[tex]168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168[/tex]
Our second equation is true for both values.
Thus, the answer is (168, 12)
Rewrite the equation 6x – 9y = 12 in terms of y.
Answer:
Step-by-step explanation:
6x - 9y = 12
subtract 6x from both sides
-9y = 12 - 6x
divide both sides by -9
y = -4/3 + 2/3x
or
y = 2/3x - 4/3
The equation 6x – 9y = 12 written in terms of y is; y = (2/3)x - 4/3
We are required to write the equation 6x – 9y = 12 in terms of y.Rewriting the equation 6x – 9y = 12 in terms of y is as follows;
6x – 9y = 12 6x - 12 = 9yDivide through by 9 so that we have;
y = (2/3)x - 4/3

The third length of the right triangle is 5 units. Then the correct option is D.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
We have
P = a
B = 12
H = 13
Then
13² = a² + 12²
169 = a² + 144
a² = 169 – 144
a² = 25
a = 5
Then the correct option is D.

A fighter pilot needs to make an emergency landing. He needs a clear space that is at least 600 m long to land safely. He is flying at an altitude of 300 m. He sees a small empty field. The angles of depression from the jet to the two ends of the field are 30° and 56° [5]
a) How long is the field?
b) Can he land safely?
(a) See the attached sketch. The jet makes a right triangle with the ground with hypotenuse y. Since the angle of depression is 56°, and the plane in which the jet is flying 300 m in the air is parallel with the ground, the angle of elevation in the right triangle is also 56°. Use the definition of sine to solve for y.
sin(56°) = (300 m)/y → y = (300 m)/sin(56°)
The uppermost angle in the blue triangle has measure equal to the difference between the two given angles of depression, 56° - 30° = 26°, and the rightmost angle is also 30° by the same reasoning as before. Then by the law of sines,
x/sin(26°) = y/sin(30°) → x = sin(26°)/sin(30°) y ≈ 317.2627 m
(b) No, the field is not long enough.

Step-by-step explanation:
5x +10° + 58° = 11x + 2°( Exterior angle of a triangle is equal to the sum of two opposite interior angles)
5x + 68° = 11x + 2°
11x - 5x = 68° - 2°
6x = 66°
x = 66° / 6
Therefore x = 11°
