Question

A corner of a rectangle is cut, creating a trapezoid.

Answer 1

Answer:

the last option of 135°.

Step-by-step explanation:

The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.

90°+90°+45°+x°=360°

225°+x°=360°                 add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.

x°=135°
