Solving for b, we have the equation A(b)=12*(b+9)/2 - we cancel out 12 and the 1/2 to get 6(b+9)=A(b) and get 6b+54=A(b). Subtract 54 from both sides to get 6b=A(b)-54 and divide both sides by 6 to get b=A(b)/6-9 = A

Answer:

Step-by-step explanation:

SOHCAHTOA

Sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse

Tangent is opposite over adjacent

In this context, opposite means the side opposite of the angle. Adjacent means the side that is touching the angle. And the hypotenuse is the longest side, which is usually visually obvious.

3.) tan(25) = x/31

Use a calculator for tan(25), then multiply both sides by 31 to get your x value.

x = 14.5

4.) cos(48) = 17/x

Use a calc to do 17/cos(48) to get the x value

x = 25.4

5.) sin(theta) = 17/18

Divide 17/18, then take the inverse sine of both sides with a calculator to get the theta value

theta = 70.8 degrees

6.) tan(theta) = 31/42

Divide 31/42, then take the inverse tangent of both sides with a calc.

theta = 36.4 degrees

7.) Your best bet is to draw a picture. For my case, Im going to imagine it. The angle is 35 degrees and the hypotenuse is 300 feet. The question is asking for the opposite of the angle. This calls for sine.

sin(35) = x/300

x = 172.1 feet
