Can someone please help and explain how to use the Pythagorean Theorem to prove a triangle is a right triangle.
marin [14]

Hi there!

For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2

And then find the root of the hypotenuse.

For example,

15^2 + 8^2 = the hypotenuse^2

Which equals, 225 + 64 = 289

Square root of 289 = 17

Please mark me brainliest if this helps!

Have a wonderful day!

PLZZ HELP ME If there are 14 green Skittles, how many yellow ones are there?
gulaghasi [49]
<span>Let's look at the information that you do have.
y = yellow
g = green

g + y = 38
</span><span>g = 38 - y

If there are 14 green skittles,then we know that:
</span>14 + y = 38
14 = 38 - y<span>
so, we can then do the equation:
38 - 14 = y
38 - 14 = 24
y = 24
</span>
So, the answer is 24 green skittles.
