How do you solve the triangle if it has legs with lengths of 18 and 28 and there is a 90 degree angle, X and Y are the other two angles?
Use Pythagorean theorem to find the length of the hypotenuse then use trigonometry to solve for the missing angles.
Below is a sketch of the triangle XYZ:
Using Pythagorean Theorem:
Now, use the property of inverse trig function (inverse tangent) to solve for angle Y:
