Question

Two adjacent angles of a paralllelogram are (2x+25)° and (3x-5)°.Find the value of x.

Answer 1

Answer:

Question :- find value of X

Given :-

adjacent angles are (2x +25) and (3x-5)

we know that the sum of adjacent angles is 180

Solution :-

(2x +25) + (3x-5) = 180

2x +25 +3x -5 = 180

5x +20 = 180

5x = 180-20

5x = 160

x = 160/5

x = 32

Hence the angles are :-

(2x+25)

= (2(32)+25)

= 64+25

= 89 degree

(3x-5)

= (3*32-5)

= 96-5

= 91 degree

"Verification"

Angle (1) + angle (2) = 180

89+91 = 180

= 180 = 180

Hence solved and verified ✔️
