c=28.6

Step-by-step explanation:

∠A=180-90-39

=51

a/sin51=18/sin39

a=22.2

c/sin90=18/sin39

c=28.6

Answer:

A=51 degrees

a=14.6 units

c=30

Step-by-step explanation:

A=180-90-39=51

a= (a=a; o=18; angle=39)

Tan(39)=a/18

0.8=a/18

14.6=a

c= (h=c; o=18; angle=39)

Sin(39)=18/c

0.6=18/c

0.6c=18

c=30

Given f (g (x)) = x + 4 and f (x) = 3x + 5, find g (x).

JulijaS [17]

Answer:

g(x) = $\frac{1}{3}(x - 1) = \frac{x}{3} - \frac{1}{3}$

Step-by-step explanation:

f(x) = 3x + 5

f[g(x)] = 3[g(x)] + 5

⇒ 3[g(x)] + 5 = x + 4

⇒ 3[g(x)] = x + 4 - 5

⇒ 3[g(x)] = x - 1

⇒ g(x) = $\frac{1}{3}(x - 1) = \frac{x}{3} - \frac{1}{3}$
