Just 14 and 15 plz:(

29.7 for question 14

15a is 12.1

15b is 14

Step-by-step explanation:

In a 45 45 90 triangle, the legs are congruent, or the same length.

If we call the legs a, then the hypotenuse would be root 2 a.

So if the hypotenuse is 42, we divide by root 2 to get the length of each leg.

That should give us 29.7

In a 30, 60, 90 triangle, the short side is a, then the hypotenuse is 2a, and the longer side is a root 3.

So if the shorter side is 7, the longer side is 12.1, and the hypotenuse is 14.
