Question

What is the value of x? (5 points) Select one: a. 20 b. 40 c. 45 d. 85

Answer 1

x = 40

The angle is a right angle, which = 90 degrees.

2 x 40 = 80

80 + 10 = 90

Answer 2

x is equal to 40

Explanation:

Since the two angles together equal 90, we can add them together and solve for x.

10 + 2x = 90

2x = 80

x = 40
