Question

Find m congruent to S

Answer 1

This is my answer
S = 90 degrees
Hope it help!!

Answer 2

90

Explanation:

The sum of the angles is 360 degrees since this is a quadrilateral

x+2x+80+145 = 360

Combine like terms

3x +225 = 360

Subtract 225 from each side

3x+225-225 = 360-225

3x =135

Divide each side by 3

3x/3 = 135/3

x =45

We want to find angle S

S = 2x = 2(45) = 90
