Question

3. Solve for x.
X
37°
11

Answer 1

• 13.77 units

-----------------------

In the given right triangle we have an angle of 37° and adjacent leg of 11 units given.

Missing is the length of hypotenuse, x.

Use cosine function:

• cosine = adjacent leg / hypotenuse

Plug in known values and solve for x:

• cos 37° = 11/x
• x = 11/cos 37°
• x = 13.77 (rounded)
