Hope this helps.
Given
Time = 8 yer a
Rate = 6% = 0.06
Interest earned = $1200
Simple Interest
Let P = the principal (the investment)
Then
P*8*0.06 = 1200
0.48P = 1200
P = 1200/0.48 = $2500
Answer: $2500
We can use tangent to calculate the length of ST.

Here, the opposite side of the 60 degree angle is ST, and the adjacent is RS. Plug in what we know, we can use 'x' for side ST:

Solve for 'x', multiply 7 to both sides of the equation:

This is an exact answer for the length of ST, we can find an approximate with a calculator:
Answer:
Step-by-step explanation:
Absolute value = 5
Absolute valve of a number is always positive regardless of direction.
