How do i find to area of a triangle?

Step-by-step explanation:

The formula for the area of a triangle is 1/2 times the base length times the height.

The base and height of a triangle always meet at a right angles, so it is not always one of the sides of the triangle.

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
