Question

In the following figure, find measures of all four angles A, B, C, D in the parallelogram ABCD. and ∠DBC = 25 degree

; ∠ BDC = 20 degree
ANSWER FAST​

Answer 1

Answer:

In ∥gm opposite angles are supplementary.

Therefore,

∠B+∠D=180

∘

2x+25+3x−5=180

∘

x=

5

180−20

=32

∠B=2x+25=(2∗32)+25=89

∘

∠D=3x−5=(3∗32)−5=91
