The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
Answer:
Step-by-step explanation:
Since they are vertical angles, 90 = 2x + 8.
Then isolate the variable by subtracting 8 from both sides.
So 2x = 82.
Then divide each side by 2 to get x = 41.
