D. 47.2 math question no guessing and show work

Given that measure of angle A = 72 degree

Given that measure of angle B = 16 degree

We know that sum of all angles of the triangle is 180 degree

A+B+C=180

72+16+C=180

88+C=180

C=180-88

C=92

Hence measure of angle C = 92 degree

Now we can use sine formula to find the missing side "a"

a=61.037232712*0.951

a=58.0464083091

Hence final answer is approx a=58.05

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
