Answer:
just simplify it ...
Step-by-step explanation:
- 4a-b+4b-a=180
- 3a+3b=180
- 3(a+b)=180
- both sides divide by 3
- a+b =60
- b=60-a
Answer:
38.7°
Step-by-step explanation:
You are basically looking at a triangle with a 90° angle (check picture).
Since we are looking for the ramp's angle and are given the length of the opposite and the hypothenuse, we have to solve the following equation:

which is equivalent to

The inver of given function will be (1,-3).
A): 2013 = 149.32
Find difference of: 194.31
2014 = 194<u>.31</u> <u>149.32</u>
= <u>44.99</u>
<u>2015</u> Total Will Be:
B):
149.32 + 25 = 174.32
(2013)
<h3> 174.32 + 44.99 = 219.31</h3>
(B) (A)
