Question

In the adjoining figure, ABCD is a trapezium in which AB || DC. If ZA = 55 and ZB = 70°, find ZC and ZD.​

Answer 1

In a trapezium, the sum of the adjacent angles within the parallel lines is 180∘.

∠A+∠D=180∘

∠D=180∘−∠A

        =180∘−55∘

        =125∘

∠C=180∘−70∘

        =110∘

∠D=125∘ and ∠C=110∘

Answer 2

Angle D is 125

Angle C is 110
