Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation




Plug 18 into 2x

3.
12 ÷ 2 = 6
27 ÷ 3 = 9
24 ÷ 4 = 6
30 ÷ 3 = 10
15 ÷ 5 = 3
Answer:
12.57
Step-by-step explanation:
Your answer would be $130.50.
We can write a ratio of earnings to hours as 108.75:15. Then, to find 18 hours, we find 1 hour and multiply by 18:
108.75 : 15
÷ 15
7.25 : 1
× 18
130.5 : 18
So therefore your answer is $130.50, I hope this helps!
