Question

I know it's not A. I need help please​

Answer 1

It is C. 139

Explanation:

Angles of TVXXYZ is 720 degrees. We know that angles Z, W and X are 82 degrees, 108 degrees and 121 degrees (311 degrees after adding them). T= 180-28=152 degrees

V=90+28=118 degrees

152+118=270 degrees

270+311=581

720-581=139 degrees

The answer is C. 139 degrees

Answer 2

139 degrees

Explanation:

The sum of the interior angles of a polygon :

sum = ( n-2) * 180 where n = number of sides

For this one there are 5 sides

so ( 5-2) * 180 = 540 degrees

angle U = 90 degrees

90 + 82 + Y + 121 + 108 = 540 Y=139 degrees
