Can anyone explain how to do this? The answer isn't as important as the explanation. My teacher gave us a video w/o an example like this so I don't know what to do lol

x = 182.53

Step-by-step explanation:

Use trigonometric ratios to find the whole side length (a) adjacent to 20° and the side length (b) adjacent to 57° respectively. Then find the difference. That would give you the value of x. That is: a - b = x

Let's solve.

✍️Finding the whole side length adjacent to 20°:

Opp = 87

Adjacent length = ? = a

Thus,

Plug in the values

Multiply both sides by a

Divide both sides by tan(20)

Finding the side length adjacent to 57°:

Opp = 87

Adjacent length = ? = b

Thus,

Plug in the values

Multiply both sides by b

Divide both sides by tan(57)

Therefore:

x = a - b

x = 239.03 - 56.50

x = 182.53
