Question

In a parallelogram ABCD,ifA=2x+15°,B=3x-25°,tyen value of x is

Answer 1

Hey..

Since sum of adjacent angles of a parallelogram is equal to 180°.

If ABCD is a parallelogram,

Angle A + Angle B = 180°

=) 2x + 15° + 3x - 25° = 180°

=) 5x - 10° = 180°

=) 5x = 180° + 10°

=) 5x = 190°

=) x = 190°/5

=) x = 38°.

Hope it's helpful to u.

Answer 2

in a llgm adjacent sides are equal to 180° due ( interior angle on the same side of transversal )

a/q A+B=180°
2x+15+3x-25=180
5x-10=180
5x=180+10
x= 190/5
x= 38°
