Question

□ ABCD is a parallelogram If LA = ( 4 x +13 )° and LD = ( 5 x - 22 ) ° then find the measure of L B​

Answer 1

Step-by-step explanation:

x=32, b=89 degrees, d=91 degrees

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
