Question

A. X=30 both angles are 150 degrees

B. x=20 labeled angles are 80 degrees and 100 degrees
C. X=20 both labeled angles are 90 degrees
D. X= 30 both labeled angles are 120 degrees

PLEASE HELP!!!!!!!

Answer 1

B. x=20 labeled angles are 80° and 100°

HOPE THIS WILL HELP U

Answer 2

The value of x = 20 and the value of the labeled angles are 80° and 100°.

The opposite angles of a quadrilateral are the same. Hence, we have ;

5x + 5x + 4x + 4x = 360

18x = 360

x = 20

The labeled angles ;

5x ;

• 5(20) = 100°

4x ;

• 4(20) = 80°

The correct option is B.
