Atype of mathematics that deals with spheres and cylinders a. plane geometry b. solid geomerty

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

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
