Answer:
x = 36
Step-by-step explanation:
<em>A triangle has 180°</em>.
That <em>third angle is 360 - 8x</em>.
So the equation is: <em>180 = 2x + x + 360 - 8x</em>.
Simplify: 180 = -5x + 360
Add/Subtract: 5x = 180
Divide: x = 36.
Factorized: (a + b + 2) ^2
Your answer D because that is how it turned out
Answer:
30°
Step-by-step explanation:
3x + (90 - 2x) = 180 - 60
x + 90 = 120
x = 120 - 90
x = 30°
