Answer:
the first one
Step-by-step explanation:
To solve this problem you use the Triangle Angle Sum Theorem concept. Which means all 3 angles of a triangle add up to 180° degrees.
The formula for this concept is:
a+b+c=180°
Answer:
r= 3
Explanation:
1. Write the division as a fraction
1/2r-3=3(4-3/2r)
2.Distribute the 3 through the paranthesis
1/2r-3=12-9/2r
3.Multiply both sides by 2
r-6=24-9r
4. Swap -6 and -9 together by changing their signs
r+9r= 24+6
5.Add them together
10r=30
6. Divide both sides by 10
r=10
