Question

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

What is the value of x?
105°
115°
125
1350

Answer 1

The sum of a trapezoid is 360 degrees

45+90+90+x=360
45+180+x=360
225+x=360
x=135

Answer 2

x=135°

Explanation:

sum of angle in side trapezoid=360°

so , 90°+90°+45°+x=360°

225°+x=360°

x=360°-225°=135°

x=135° answer
