The angles of triangle abc are in the ratio of 8:3:4. what is the measure of all the angles?

48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24

Step-by-step explanation:

Since The angles of a triangle add up to 90, then 8 + 3 + 4 should equal to 90 if multiplied by x.

Example:

x(8 + 3 + 4) = 90

x(15) = 90

15/15x = 90/15

x = 6

If x is equal to 6, then 6 times 8, 6 times 3, and 6 times 4, should equal their respective angles and add up to 90.

Example:

8 * 6 = 48

3 * 6 = 18

4 * 6 = 24

48 + 24 + 18 = 90

This means the angles are

48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
