Answer:
3x - 4 = 32
Step-by-step explanation:
We solve for x to find the number (knowing that x is the unknown number).
3x - 4 = 32
3x = 32 + 4
3x = 36
x/3 = 36/3
x = 12
Answer: 170
Step-by-step explanation: To find the percent change, simply multiply this number by 100.
Answer:
130° is the correct answer
∠QPR=80°
∠PQR+∠QPR+∠QRP=180°
∠PQR+∠QRP=100°
2(x+y)=100°
x+y=50°
So, in △QOR
x+y+∠QOR=180°
∴∠QOR=180°−50°
=130°
