Question

in a parrallelogram ABCD if angle a is 2x+25° and angle b is 3x-5° find the value of x​

Answer 1

Answer:

x=32°

Step-by-step explanation:

In a parallelogram adjacent angles are equal to 180°

Hence angle A +angle B= 180°

i.e (2x+25)°+(3x-5)°=180°

5x+20=180°

5x=180-20

5x=160°

x=

$\frac{160}{5} = 32$

Answer 2

Step-by-step explanation:

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

∘
