Answer:
20
Step-by-step explanation:
Angles form a right angle, hence they add up to 90
x + 2x + x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Answer:
20
Step-by-step explanation:
We can tell from the little square in the corner that this is a 90 degree angle, so all three of the expressions of x should add up to 90:
x + 2x + (x + 10) = 90
Combine like terms:
4x + 10 = 90
4x = 80
Divide by 4:
x = 80/4 = 20
The answer is 20.
Hope this helps!
