Question

Q10) ABCD is a parallelogram If A = (2x + 25 )° and B = (3х - 5 )°. Find
the value of x and the measure of LA and B ?
​

Answer 1

Answer:

we know that adjacent angles of a parallelogram is supplementary means 180° angla (a) and angle(b) are adjacent angles

Step-by-step explanation:

(2x+25)°+(3x-5)°=180°

(5x+20)°=180°

5x=180-20

5x=160°

x=160/5

=32°

so angle A=89°

and angle B=91°
