We are given that
In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.
Solution
We will first draw a diagram to illustrate the information
Above we want to find x
The method to use is SOHCAH
From the right angle triangle above we have above, we have the adjacent side and we want to find the hypotenus, so we use cosine
i.e
We need to solve for x here
Thus, |BC| = 86.1 (to the nearest tenth

______________________________
<h3>1.) Multiply both sides of the equation by 3:</h3>×
×
<em> - We do this because we need to get x alone and separate from fraction from. </em>
<u>Equation at the end of Step 1:</u>
- <u />
<u />
Cancels Out
<em> - We do this to cancel out an extra numbers in order to get only x alone with 1 number on the opposite side of the equal. </em>
