Question

In a trapezium ABCD AB||CD, < a measures 65°, the D measures ?​

Answer 1

Answer:

115°

Step-by-step explanation:

180 - 65 = 115°

angle D = 115°

Answer 2

Step-by-step explanation:

In trapezium ABCD ,

AB // CD

Since the angles on the same side of transversal are supplementary( sum of the angles is 180 degree),

<A + < D = 180

65 +< D =180

< D = 180 - 65

= 115

Hint: A transversal is a line joining the ends of two parallel sides.
