Answer:
x = -3
Step-by-step explanation:
<u>Step 1: Subtract 8 from both sides</u>
8 - 3x - 8 = 17 - 8
<em>-3x = 9</em>
<em />
<u>Step 2: Divide both sides by -3</u>
-3x / -3 = 9 / -3
<em>x = -3</em>
<em />
Answer: x = -3
Sum of interior angles in a triangle = 180
so
2y + y+10 + 50 = 180
3y + 60 = 180
3y = 120
y = 40
Answer is A. 40
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
