A quadrilateral has angle measures of 50°, 72°, and 78°. What is the measure of the fourth angle? 160°
60°
50°
100°

160°

Step-by-step explanation:

Quadrilateral's angles add up to 360 degrees.

So:

x = fourth angle measure (unknown currently)

50° + 72° + 78° + x = 360°

200° + x = 360°

x = 160°

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.
