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°

If angle JKM= 15x-48 and angle L= 5x+12 and angle M= 40, find angle MKL
horrorfan [7]
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

Use the functions to find x
suter [353]

Answer:

x = 14

Step-by-step explanation:

f(x) = 10 -  \frac{9}{2} x \\  \\ plug \: f(x) =  - 53 \\  \\  - 53 = 10 -  \frac{9}{2} x \\  \\ \frac{9}{2} x  = 10 + 53 \\  \\ \frac{9}{2} x  = 63 \\  \\ x = 63 \times  \frac{2}{9}  \\  \\ x = 7 \times 2 \\  \\ x = 14
