Question

Parallelogram PQRS is shown.measure of angle s=(3x),measure of angle R=120, and measure of angle Q=(2y) find the value of X

Answer 1

Parallelograms have adjacent angles supplementary (sum to 180).

For pair r and s,

3x+120=180, => x=(180-120)/3=20 °

Similarly, for pair q and r,

2y+120=180 => y=(180-120)/2 = 30 °
