In triangle abc, ac=12, the measure of angle a = 30\deg, and the measure of angle b = 45\deg. find the area of this triangle.

First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.

So we will get

Now we use sine law, which is

Substituting the values, we will get

The formula of area of triangle, for the given triangle is

answer: 40.95

step-by-step explanation:

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
