Question

two consecutive angles in a parallelogram have the measures x+5 and 4x-10. Find the smaller angle.

Answer 1

If angles are consecutive then Their sum will be 180°.

So,
x+5+(4x-10) = 180
5x-5 = 180
5(x-1) = 180
x-1 = 36
x = 37

Angles are x+5 that is 37+5 = 42°
and 2nd one is 4x-10 that is 4x37-10 = 138°

Smaller Angle Is 42°
