First calculate the missing angle
. By knowing all angles in triangle have a sum of 180°.
Now we required to use angle functions in a right triangle. The cosine of
is equal to the relation of side
and hypotenuse
.
Now we solve this for hypotenuse.
Now put in the numbers.
So we know the length of hypotenuse and length of side
therefore side
can be calculated using Pythagorean theorem:
.
Solve for side
.
So there you go. If you have any questions feel free to ask.
