Question

NO LINKS Consider the isosceles trapezoid.
What is the value of y?

Answer 1

y = 9 x= -11

Explanation:

opposite angles of a trapezoid are supplementary.

The two angles of the same base in an isosceles triangle are congruent.

-6x-16 = 50

-6x = 66

x= -11

The supplementary of 50 is 130

3x+16y+19 = 130

-33 +16y +19 = 130

16y = 144

y = 9

The sum of all 4 angles is 360 degrees
