Answer:

Step-by-step explanation:
ΔABC and ΔADB are similar (AAA).
Therefore the corresponging sides are in proportion:

Substitute:

<em>cross multiply</em>

(14+19+x)/3=17
x= 18
the first is the equation and the second it the answer
Answer:
5
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opp /hyp
sin 30 = x / 10
10 sin 30 = x
10 * 1/2 = x
5 =x
Answer:
If f(x)=g(x), the solution is x=-2
Step-by-step explanation:
We are given:

We need to find the solution if f(x)=g(x)
Now solving for f(x)=g(x)

If f(x)=g(x), the solution is x=-2
