What is the length of bc in the right triangle below?

Answer : The length of BC in the right triangle is, 75

Step-by-step explanation :

Using Pythagoras theorem in ΔBAC :

Given:

Side AB = 21

Side AC = 72

Now put all the values in the above expression, we get the value of side BC.

Therefore, the length of BC in the right triangle is, 75

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
