Question

In a 45° - 45° - 90° right triangle, the length of the hypotenuse is 15 . What is the length on one of the legs?

15
2
17
13

Answer 1

since 45 = 45
then the two other sides are equal
(15)^2 = (side)^2 + (side)^2
225 = 2 (side)^2 divide 2 to both sides
112.5 = (side)^2 square root
side = 10.6
this is my answer
