Yes, I can do some problems, but most I have trouble with.

Tranquility · Answer

c is the hypotenuse. It's the largest side of the triangle which is opposite the 90 degree angle

The other two sides are the legs of the triangle

Speccy · Answer

so, 15x15=225 and 17x17=289 so 514

Tranquility · Answer

You don't add those numbers.

Look at the triangle in your question and the triangle I drew.

Match the numbers with the letters

Basically what number multiplied by itself gives you 64? If you don't know, you can use a calculator https://www.google.com/search?q=sqrt(64)
