Answer:
Given that, ABCD is a trapezium with AB∥CD, ∠A=36
o
and ∠B=81
o
.
To find out: The measure of ∠C and ∠D.
We know that, if two parallel lines are intersected by a transversal line, the corresponding interior angles are supplementary.
∴ ∠A+∠D=180
o
⇒∠D=180
o
−36
o
=144
o
Similarly,
∠B+∠C=180
o
⇒∠C=180
o
−81
o
=99
o
Hence, ∠C=99
o
and ∠D=144
o
.

Answer:
c=99° , D=144°
Step-by-step explanation:
D= 180-36= 144°
C = 180-81= 99°
