Question

find angle B and angle C of a parallelogram if angle B is equal to 4x and angle D is equal to 3x​

Answer 1

Answer:

let the parallelogram be ABCD

I have attached photo to refer

<B=<D as opposite angles of parallelogram are equal so 4x-5= 3x+10

x= 15

so <B is 4x-5= 55°

<B+<C= 180 as adjacent angles of parallelogram are supplementary.

55°+ <C= 180°

<C= 180°-55°

= 125°
