Explanation:
The sine of an angle is equal to the side opposite to that angle divided by the hypotenuse.
Here, we see our hypotenuse, the side opposite to the right angle, is
Looking at
Where
Plugging in
Square rooting both sides to solve for
So, now we know the side opposite to
Use Pythagorean Theorem followed by SOHCAHTOA
Explanation:
Using the Pythagorean Theorem...
... You can find the missing side length. A and B are the bases, and C is the hypotenuse.
After getting the missing side, refer to the acronym SOHCAHTOA to find out what to put on your calculator. In your case, you'll just put the simplified fraction.
SOHCAHTOA stands for
S in:
O pposite / H ypotenuse
C os:
A djacent / H ypotenuse
T an:
O pposite / A djacent
