Question

ABCD is a quadrilateral in which ∆ A = ∆C and ∆B = ∆D. IF ∆A is twice ∆ B, find the measure of each
angle​

Answer 1

Answer:

angle a is 120 and b is 60

Answer 2

Step-by-step explanation:

In a cyclic quadrilateral, opposite angles are supplementary.

⇒∠A+∠C=180^0

Gien that

⇒2∠A=3∠C

⇒∠A=1.5∠C

⇒1.5∠C+∠C=180^0

⇒2.5∠C=180^0

⇒∠C=72^0
