When you ask what is "90 out of 36?" you want to know what percent 90 is out of 36.

here are step-by-step instructions showing you how we calculated 90 out of 36 as a percentage

the first step is to divide 90 by 36 to get the answer in decimal form

$90 \div 36 = 2.5000$

2. then we multiply the answer from the first step by 100 to get the answer as a percentage

$2.5000 \times 100 = 250.00\%$

But if you think that the answer was wrong, 

you can copy the answer from the top.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is four times

prohojiy [21]

Answer:

{36, 66, 78}

Step-by-step explanation:

Let the measures of the three angles be f, s and t, for first, second and third. Then s + t = 4f, t = 12 + s, and f + s + t = 180.

Subbing 12 + s for t in the first equation, we get s + 12 + s = 4f.

Subbing the same in the third equation, we get f + s + 12 + s = 180

This results in two equations in two unknowns (f and s):

2s - 4f = -12

2s + f = 168.

Let's eliminate s by subtracting the first of these two equations from the second. Doing so yields 5f = 180. Then the first angle, f, or x, is 36.

Then, from 2s + f = 168, we get 2s + 36 = 168, or 2s = 132. Thus, the second angle is s = y = 66.

The sum of the three angles must be 180. Thus, 36 + 66 + t = 180, or

102 + t = 180, or t = z = 78.

The three angles are

{36, 66, 78}.
