Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP
4vir4ik [10]

Answer: 2\sqrt{22}

Step-by-step explanation:

Pythagorean theorem: a^{2} +b^{2} = c^{2}, where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

9^{2} +b^{2} = 13^{2}

81 +b^{2} = 169

Since we don't know what b^{2} is, we're going to isolate it by subtracting 81 on both sides

b^{2} = 88

We have to square root both sides in order to find out b (or x in the problem).

\sqrt{b^{2}} = \sqrt{88}

When you put this on a calculator it would result in 2\sqrt{22} which is the answer d in the problem.

Valarie made fruit drinks for a birthday party. She used 3/6 of a cup of grape juice, 5/6 of a cup of strawberry juice, and 2/6
Nana76 [90]

Answer:

Valarie make 1\frac{2}{3}\ cups of fruit drink.

Step-by-step explanation:

Given:

Valarie made fruit drinks for a birthday party.

She used 3/6 of a cup of grape juice, 5/6 of a cup of strawberry juice, and 2/6 cup of soda. She mixes all the juices together.

Now, to find cups of fruit drink Valarie make.

As given that she mixes all juices altogether.

So, to get the cups of fruit drink we add all quantities of juice:

3/6 cup of grape juice + 5/6 cup of strawberry juice + 2/6 cup of soda.

=\frac{3}{6} + \frac{5}{6} +\frac{2}{6}

=\frac{3+5+2}{6}

=\frac{10}{6}

<em>Dividing numerator and denominator by 2 we get:</em>

=\frac{5}{3} =1\frac{2}{3}

Therefore, Valarie make 1\frac{2}{3}\ cups of fruit drink .
