From the graph given

For f(x), where x = 3, on the graph f(3) is

$f(3)=6$

For g(x), where x = 3, on the graph g(3) is

$g(3)=6$

Hence,

$f(3)=g(3)$

The answer is the second option

An equilateral triangle has a perimeter of 48 cm. What is the area?

KiRa [710]

Answer:

$A=64\sqrt{3}\ cm^2$

Step-by-step explanation:

we know that

An <u><em>equilateral triangle</em></u> has three equal sides and three equal interior angles (each interior angle measure 60 degrees)

The perimeter is equal to

$P=3b$

where

b is the length side of the equilateral triangle

we have

$P=48\ cm$

substitute

$48=3b$

solve for b

$b=48/3\\b=16\ cm$

Find the area

The formula of area applying the law of sines is equal to

$A=\frac{1}{2}b^2sin(60^o)$

substitute the value of b

$A=\frac{1}{2}(16)^2sin(60^o)$

$sin(60^o)=\frac{\sqrt{3}}{2}$

$A=\frac{1}{2}(16)^2(\frac{\sqrt{3}}{2})$

$A=64\sqrt{3}\ cm^2$

Answer:

5 4/5

Step-by-step explanation:

First of all subtract the whole number, 2, from 8 1/5

You would get 6 1/5

Now subtract 2/5 from that, or set up an equation like:

6 + 1/5 - 2/5

you would get 6 - 1/5 or 5 4/5

Find the measure of the angle indicated in bold

11Alexandr11 [23.1K]

The answer is 50.

i came to this conclusion when using this equation: 15x+5=2+16x
for x, i got 3.

using my x-value, i replace “x” with “3” when solving angle measure, “15(3)+5”

15(3)+5= 50
there is your answer!
