Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
?=115-50=65°
Answer:
Step-by-step explanation:
For window, area 3×2
=6
For wall, area=20×16
=320
Area of wall withot window=320-6
=316
20% of 89.75 is 17.95
so :
the Trina's coupon will subtract the answer by 10%:
10%of 71.8 is 7.18
so the final answer is:
she has to pay $64.62
hope this helps
a. f(a) =5a+12
we have 1. a=6
Therefore, where ever we find a we'll substitute in 6
f(6) =5(6) +12
6f=30+12
6f=42
so therefore 1. a=6 will match c on the right
2. a=2
f(2) =5(2) +12
2f = 10+12
2f = 22
therefore 2. a=2 will match a on the right
3. a=4
f(4) =5(4) +12
4f=20+12
4f=32
therefore 3. a=4 will match d on the right
4. a=5
f(5) =5(5) +12
5f=25+12
5f=37
therefore 4. a=5 will match b on the right
Answer: (2,2)
