Decimal Form:
0.84
Step-by-step explanation:
<em>Reduce the expression, if possible, by cancelling the common factors.</em>
x+ y = 90
x = 36 + 3y
x = 36 + 3(90 - x)
x = 36 + 270 - 3x
4x = 306
x = 153/2 = 76.5 degrees
Answer: 76.5 degrees
Check: y=90=76.5 = 13.5 degrees
3y+36 =3(13.5)+36 = 76.5 good
