Question

in a parallelogram ABCD find the measure of all angles if one of its angle is 15 degree less than twice the smallest angle​

Answer 1

Answer:

Let smallest angle = X

larger angle = 2x +15

we know that , opposite sides are parallel to each other in parallelogram ..

so,

x+2x+15 = 180°

3x = 165°

x = 55°

so,

all angles = ( 55°,125°,55°,125° )
