Question

Find W (hypotenuse) if the angle is 15 degrees and the opposite side has a length of 7 cm​

Answer 1

Answer: W ≈ 16.6

Explanation:

The Pythagorean Theorem equation is
`a^(2)` +
`b^(2)` =
`c^(2)`

First do
`15^(2) +7^(2) =w^(2)`

Which equals
`274=w^(2)`

Then do
`√(274) =w`

so w ≈ 16.6

Answer 2

`\sin(15^o )=\cfrac{\stackrel{opposite}{7}}{\underset{hypotenuse}{h}}\implies h=\cfrac{7}{\sin(15^o )}\implies h\approx 27.05`

Make sure your calculator is in Degree mode.
