Trapezoid yesr is an isosceles trapezoid. if m∠yes= 77 °, what is m∠esr?
a) 77°
b) 113°
c) 103°
d) 13°

C) 103°

Step-by-step explanation:

Because this is an isosceles trapezoid, it will have 2 pairs of equal angles. If angle YES is equal to 77°, that means that the angle that is on the same side as it will also equal 77°. Angles YRS and ERS are also equal. Assume that angle equals x. Knowing this, you can use the equation:

77+77+2x = 360

154+2x = 360

2x =360-154=206

x=206/2

x=103°
