Answer:
x = 32
m∠7 = 94
m∠8 = 86
m∠3 = 94
Step-by-step explanation:
(2x + 30) + (3x - 10) = 180
5x + 20 = 180
5x = 160
x = 32
m∠7 = 2(32) + 30 = 94
m∠8 = 3(32) - 10 = 86
<u>or</u>
m∠8 = 180 - 94 = 86
<u>m∠3 ≈ m∠7</u> (corresponding angles)
Question: What is 16% of 80?
You have to change the percentage to a decimal.
Remove the percentage sign and divide by 100 (% are based off 100)
16%⇒.16
Now multiply .16 and 80

Answer: 12.8
Answer:

Step-by-step explanation:
2 feet
Step-by-step explanation:
4+4= 8
12-8=4
4 divided by 2= 2 feet :)
The answer should be y=3x+18
