I’m think the angles are supplementary and you just have to find the value for each angle that is going to equal 180 degrees

M5+M7+81= 180

PilotLPTM [1.2K]

Answer:

x=1

Step-by-step explanation:

Use the distributive property on 2(4x - 4), which makes the equation 3x+8x-8=3

Simplify, which makes the equation 11x-8=3

Add 8 to both sides, which makes the equation 11x=11

Divide both sides by 11, which makes the equation x=1
