Answer:

tan 5\4

Step-by-step explanation:

on number 1 use TOA which is Tan 4\5 if not 5\4
c^2 = a^2 + b^2

1. c^2 = 4^2 + 5^2
c^2 = 16 + 25
c^2 = 41
c = √41
c = 6.40

2. 25^2 = 15^2 + b^2
625 = 225 + b^2
400 = b^2
b = √400
b = 20

3. 60^2 = a^2 + 48^2
3600 = a^2 + 2304
1296 = a^2
a = √1296
a = 36
