Let's say the number is represented by x.
Five times the number is 5x.
5x - 58 = -23 (Add 58 to both sides)
5x = 35 (divide both sides by 5)
x = 7
The number is 7.
Use Pythagorean theorem
a^2 + b^2 = c^2
C = hypothenuse
8^2 + b^2 = 15^2
64 + b^2 = 225
b^2 = 161
b = square root 161 = 12.68
Solution: 12.7 cm
