We have 2 angles that are supplementary, so their sum equals 180⁰.
(4x - 10) + (7x - 8) =180
11x - 18 = 180
11x = 198
x = 18
Assuming you want the value of x:
The angles are on a straight line which means they must add up to 180 degrees. Make this into an equation.
(4x - 10) + (7x - 8) = 180
Combine like terms.
11x - 18 = 180
Add 18 to both sides.
11x = 198
Divide both sides by 11.
x = 18
If you want the measurements of the angles, plug x into the angles.
4x - 10 ⇒ 4(18) - 10 = 62°
7x - 8 ⇒ 7(18) - 8 = 118°

Answer:
15
Step-by-step explanation:
(-7,0) and (8,0) are on the opposite side of origin of x axis
d = 8 - -7 = 15
JKM = M + L
15x - 48 = 40 + 5x + 12
10x - 48 = 52
10x = 100
x = 10
JKM = 15(10) - 48 = 102
180 = JKM + MKL
180 = 102 + MKL
MKL = 180 - 102 = 78
