Right triangle def is shown. which is equal to sin∠e? a)cos∠db)cos∠fc)sin∠dd)sin∠f

B) cos∠F

Step-by-step explanation:

SOH CAH TOA tells you ...

... Sin = Opposite/Hypotenuse

... sin(E) = DF/EF

It also tells you ...

... Cos = Adjacent/Hypotenuse

... cos(F) = DF/EF

So ...

... sin(E) = cos(F)

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
