Step-by-step explanation:

1. Three sides lengths uniquely specify a triangle.

__

2. Three angle measures specify the shape of a triangle, but not its size. More than one triangle is possible with any given set of angle measures.

__

3. If the lengths do not satisfy 3 + 7 > 10, which they do not, then no triangle can be formed.

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
