Question

A trapezium has angle d = 2x+10° angle c 92 ° angle b =y° angle a = x+20° find the values of x and y​

Answer 1

Answer:

Here, ABCD is isosceles trapezium.

An isosceles trapezium has a pair of parallel sides.

∴ AB∥CD

Its non parallel sides are equal.

∴ AD=BC

Diagonals of an isosceles trapezium are equal.

⇒ AC=BD

Base angles of equal sides has equal angles.

∴ ∠C=∠D
