Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) (6 points) a right triangle is shown with one leg measuring 7 and the hypotenuse is labeled 12. an angle across from the leg measuring 7 i

Ok, this looks like a law of sine problem. You are given two side lengths and their opposite angles. The hypotenuse is 12 and the measure of its opposite angle is 90 (right triangle). One of the legs is 7 and you are asked to find its opposite angle: y.

To set this up using law of sines, use the formula: sin A over a = sinB over b
 (A and B are the angles while a and b are the side lengths).
Plug in the values you are given and you have: sin 90 over 12 = sin y over 7
