Answer:
angle C=135
Step-by-step explanation:
Given- ABCD is a trapezium with AB∥CD, ∠A=∠B=45
o
To find out- ∠D and ∠C=?
Solution-
∠A and ∠D are the adjacent angles of the trapezium within AB∥CD.
∴∠A+∠D=180
O
⇒45
O
+∠D=180
O
⇒∠D=135
O
Similarly ∠B and ∠C are the adjacent angles of the trapezium within AB∥CD.
∴∠B+∠C=180
O
⇒45
O
+∠C=180
O
∠C=135
O
