Find the missing side of triangle in simple radical form

Andre45 [30]

Answer:

$\sqrt{262}$

Step-by-step explanation:

$Formula For Right Triangle Sides : a^{2} + b^{2} = c^{2}$

Remember c is the angel facing towards the 90 degrees angel.

Variables:

$a = \sqrt{37}$

$b = 15$

$c = x$

————————————

$\sqrt{37} * \sqrt{37} + 15 * 15 = c^{2}$

$37 + 225 = c^{2}$

$262 = c^{2}$

$\sqrt{262} = c$

Solve the proportion 7/5=21/x (show work/explain how u got it please)

Anvisha [2.4K]

Answer:

x = 15

Step-by-step explanation:

I am going to use the "butterfly" method for proportions

(there is another type of butterfly method that is different, I am not sure if there is another name for this method, sorry!)

$\frac{7}{5} = \frac{21}{x}$

Multiply the:

- top left by the bottom right

-the top right by the bottom left

and then:

- set them equal to each other

So we will multiply 7 by x and 21 by 5 (if this doesn't make sense tell me and I will explain it even more!)

7x = 21 * 5

7x = 105

(Divide both sides by 7) x = 15

Hope this helps, have a nice day! :D <3

Tenaya earned 82 points on one math test and 94 points on the next test. Elena earned 94 points on the first test and then 82 po

jek_recluse [69]

Answer:

Total test score of Tenaya and Elena are same.

Step-by-step explanation:

Given:

Points earned by Tenaya on one math test = 82

Points earned by Tenaya on next math test = 94

Points earned by Elena on first math test = 94

Points earned by Elena on next math test = 82

We need to Compare the total test scores for Tenaya to the total scores for Elena.

Solution:

First we will find the Total test score of Tenaya and Elena.

Now we can say that;

Total test score of Tenaya is equal to sum Points earned by Tenaya on one math test and Points earned by Tenaya on next math test.

framing in equation form we get;

Total test score of Tenaya = $94+82 = 176\ points$

Total test score of Elena is equal to sum Points earned by Elena on one math test and Points earned by Elena on next math test.

framing in equation form we get;

Total test score of Elena = $94+82 = 176\ points$

Hence from we can say that Total test score of Tenaya and Elena are same.
