a^2 + b^2 = c^2 where c is the length of the hypotenuse.

x the longest side

tcarroll010 Group TitleBest ResponseYou've already chosen the best response.1
Yes, that's right. Of the two remaining sides, it doesn't matter which one you call "a" or "b", just as long as neither is the hypotenuse because the hypotenuse is "c", or in your diagram, "x". So, you could change the formula to a^2 + b^2 = x^2 because it is understood that that is x. Once you add together the squares of "a" and "b", you THEN take the square root to get x.

can you please show me so i can use it as an example
 2 years ago

tcarroll010 Group TitleBest ResponseYou've already chosen the best response.1
Ok, but you will fill in the "a" and the "b". You are looking for steps as indicated in your problem. x^2 = a^2 + b^2, so x = sqrt(a^2 + b^2). As for actual steps: 1) square "a" and "b" separately, 2) add the resulting values to get one number, 3) take the square root of that number and then you have "x".

What's "a" and what's "b"? They are in your diagram.

Good. So, x^2 = a^2 + b^2 becomes x^2 = 7^2 + 32^2. Now, square 7 and 32 separately and get two numbers, one for each. Add them to get one number. Take square root of that one number and you get "x".

Your post came before I posted, so first go back to my last post.

It's 1073, not 1075, but you were close. 1073 is x^2, so you take the square root of 1073 to get x.

use sin sin(32) = 7/x
 2 years ago

tcarroll010 Group TitleBest ResponseYou've already chosen the best response.1
That changes everything. sin 32 = 7/x. x = 7 / sin 32.

then do the sin 32 and use the number

I did the sine and found that the answer is one that is listed.
