Sin10° + tan40° × cos10° = ? how to solve this? ?

You can use the double angle formula

and

and the angle shift identity:

So:

∠cbe and ∠deb are same-side interior angles.

i took the test

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
