But this doesn't help us find the measure of ∠ L \angle L ∠Langle, L. We're stuck ! What we need: We need new mathematical tools to solve problems like these.

Sal is given a right triangle with an acute angle of 65° and a leg of 5 units, and he uses trigonometry to find the two missing sides.

Sal is given a triangle with two side lengths and one angle measure, and he finds all ... But, to find a missing angle, it's best to use sin(a)/A = sin(b)/B = sin(c)/C. Is&nbs...

Add the values of the three angles in any triangle, and you'll get 180 degrees. If you have a right triangle, one of its angles is 90 degrees by definition. That means ....

Divide the measure of the opposite side of your angle by the measure of your hypotenuse. For example, if your opposite side is 4 and your hypotenuse is 5, then ...
