Question

In the same parallelogram, ∠A:∠B=3:1 find the measure of a b c d

Answer 1

Step-by-step explanation:

Hi ,

your question's answer is ready.

in the same parallelogram ,

say the common factor is x

then <A=3x,

and <B=x

we know that the sum of the angle of one side of a parallelogram is 180°.

then <A+<B=180°

3x+x=180°

4x=180°

and x=45°

:. <A=135°.and <B=45°

then<A=<C=135°

and<B=<D=45°.

HOPE IT IS HELPFUL.
