Answer:
x=30°
y=15°
z=150°
Step-by-step explanation:
2x+90+x=180°
2x=180°-90°
x=90/3
x=30
2y=x
y= 30/2
y=15°
2y°+z°=180°
2(15°)+z°=180°
z=180°-30°
z=150°
Hope it helps! :)

Answer:
t = 7s + 4
Step-by-step explanation:
The goal is to get t alone. So we should move 7s to the other side of the equals to sign. When we move 7s to the other side of the equals to sign the sign changes to -7s. There are no like terms to be collected so the answer should be 7s + 4 for t.
