Step-by-step explanation:

The tirangle ABC is given as equilateral. Every angle is therefore =. Not only that, each angle is 60 degrees.

If you need proof of that, remember that x + x + x = 180. Every triangle has 180 degrees.

if 3x = 180 then 1 x is 60

8x - 44 = 60 Add 44 to both sides.

8x = 60 + 44

8x = 104 Divide by 8

x = 104/8

x = 13

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$
