In a right-angled triangle the hypotenuse and a perpendicular side are 113 and 112, respectively. Determine the length of the missing side

15 is the length of the missing side

Step-by-step explanation:

Use the Pythagoras Theorem to find the missing side:

Therefore the missing side is 15 units long.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
