  x = 7

Step-by-step explanation:

We assume the hash marks are intended to indicate both triangles are isosceles. Then the right-end angle of the upper triangle is ...

  180° -2(75°) = 30°

Its complement is the supplement of the "missing variable" angle.

  90° -30° = 180° -(18x -6)°

  18x = 126 . . . . . rearranging (add 18x -60)

  x = 7 . . . . . . . . . divide by 18

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.
