Question

ABCD is an isosceles trapezium . if angle d = c = 59 ° what is the measure of angle a'
​

Answer 1

Answer:

As ABCD is an isosceles trapezium.

Then, the angleA must be equal to angle B and the angle C must be equal to angle D.

Here, given,C=D=59⁰

As ABCD is a quadrilateral,

so A+B+C+D=180⁰

Or,2A+59⁰+59⁰=180⁰ — — (As A=B)

Or,2A=180⁰–118⁰=62⁰

Or,A=62⁰/2=31⁰.

Here is your answer.
