Answer:

1) m<RAS = 126

2) x = 144

Explanation:

1)

10x + 36 + 6x = 180

16x + 36 = 180

16x = 144

x = 9

<RAS:

10x + 36

10(9) + 36 = 126

2)

54 + 90 + y = 180

y + 144 = 180

y = 36

x + y = 180

x + 36 = 180

x = 144

First one:
Supplementary = 180
Add the angles together to get 180
10x + 36 + 6x = 180
16x = 144, x = 9
Plug 9 into equation of angle RAS
10(9) + 36 = 126
Angle RAS = 126 degrees

Second question:
Exterior angle = sun of two opposite interior angles
54 degrees + 90 degrees = 144

Solution: the exterior angle is 144 degrees
