Find the missing side of each triangle. Round your answer to the nearest tenth if necessary.

Step-by-step explanation:

Given

See attachment for triangles

Required

Determine the missing sides

All 4 triangles are right-angled. So, to calculate the missing sides, we apply Pythagoras theorem which states that:

Solving (1):

So, we have:

Make the subject

Take positive square root of both sides

Solving (2):

So, we have:

Take positive square root of both sides

Solving (3):

So, we have:

Make the subject

Take positive square root of both sides

Solving (4):

So, we have:

Make the subject

Take positive square root of both sides

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.

answer: 0.64
