Need doing this question, show steps as well so i can understand it.

Explanation:

The reference angle is angle S = 41 degrees. The side opposite that (RT) is unknown and what we want to find. The adjacent side to the reference angle is TS which is 8 units long.

RT = x

TS = 8

The ratio of the opposite and adjacent side is equal to the tangent of the reference angle, so,

tan(angle) = opposite/adjacent

tan(41) = x/8

We are given the value of tan(41) to be approximately 0.869, which means we will replace "tan(41)" with this decimal value and then isolate x by multiplying both sides by 8. This happens in the section below.

tan(41) = x/8

0.869 = x/8

8*0.869 = 8*x/8

6.952 = x

x = 6.952

x = 6.95

RT = 6.95

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
