Question

In the trapezoid, what is the measure of 1?

85°
115°
90°

Answer 1

115°

Explanation:

all angles of a trapezoid add up to 360° and corresponding pairs of base angles add up to 180°. this means that 65° and angle 1 would have to add up to 180°

180 - 65 = 115°

Answer 2

85°

Explanation:

Since it is a trapezoid one pair of opposite sides will be parallel.

As, AB||CD,

95°+ m<1 = 180°( co- interior angles)

m<1= 180°- 95°

m<1= 85°
