Question

"In the 45°-45°-90° triangle above, r = 10. Find the other two lengths.

Answer 1

We are given a right triangle that has angles of 45°-45°-90°. This would indicate that the triangle is an isosceles type. We can use some trigonemetric functions to solve for the other legs. We do as follows:

 

sin 45 = p / 10

p = 5√2

 

cos 45 = q /10

q = 5√2

 

Hope this answers the question. Have a nice day.
