------> by supplementary angles
Substitute the values and solve for x




Find the value of angle R
Find the value of angle Q

Y = 8/cos60 = 16
x = sqr(16^2 + 8^2) = 8sqr(3) = 13.86 approx
Answer:
8.0%
Step-by-step explanation:
We have been given that James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be $76.57.
First of all, we will find the amount paid for the year using the monthly rate by multiplying $76.57 by 12 (1 year = 12 months).

Now, we will use percent change formula.






Therefore, Mr. Harmon is paying 8.0% more for the year using the monthly rate.
