Question

If

A. x = 62; mZROS = 31°
B. x = 60; mZROS = 28°
C. x= 31; mZROS = 62°
D. X = 28; mZROS = 60°

Answer 1

C. x= 31; mZROS = 62°

Explanation:

90=28+2x

2x= 90-28

2x= 62

x= 62/2

x=31°

2(x)= 2× 31 = 62

I hope I helped you^_^

Answer 2

x = 31

ROS = 62

Explanation:

QOR + ROS = 90 degrees as indicated by the box

28+ 2x = 90

Subtract 28 from each side

2x = 90 -28

2x = 62

Divide by 2

2x/2 = 62/2

x = 31

ROS = 2x = 2*31 = 62
