Complementary angles add up to 90.
Say the complementary angle is A.
Angle A + Angle B = 90
Angle A + 60 = 90
Angle A = 30 degrees
Hope this helps :)

Given:
loan amount = 300
finance charge = 20
term = 14 days.
To solve for APR.
<span>1. Divide the finance charge by the loan amount.
20/300 = 0.0667
2. Multiply the result by 365.
0.0667 x 365 = 24.35
3. Divide the result by the term of the loan.
24.35/14 = 1.74 (APR in decimal format)
<span>
4. Multiply the result by 100.
1.74 x 100 = 174% APR</span></span>
F(-4)=G(-4) because when the two lines cross over the f line is at the -4 and same with G
Answer:
x=66
Step-by-step explanation:
A straight line is equal to 180 degrees so we can make the equation 180=2x-48. After this we can do 180-48=2x then we can do 132/2=x
