Question

Find the length of the missing side..Help?

Answer 1

@ganeshie8 Do you know anything about this type?

Answer 2

use pythagorean theorem

Answer 3

That's the thing - I don't know how to do that haha.

Answer 4

a^2 + b^2 = c^2

Answer 5

34^2 + b^2 = 38^2

solve b

Answer 6

Do I like minus 34^2 from both sides?

Answer 7

yes

Answer 8

Would that make it b^2 = 288 or b^2 = 4?

Answer 9

34^2 + b^2 = 38^2

b^2 = 38^2 - 34^2

use your calculator

Answer 10

Oh, I was supposed to rearrange the equation to b^2 = 38^2 - 34^2 instead of subtracting from both sides like a two-sided equation? O.o

Answer 11

both give you the same result
you're allowed to do anything as long as you do it to both sides

Answer 12

I used my calculator and it gave me 288..So it would become b^2 = 288^2? or would it just be plain 288?

Answer 13

34^2 + b^2 = 38^2
-34^2 -34^2


0 + b^2 = 38^2 - 34^2

Answer 14

Oh right ! 288 is correct

Answer 15

b^2 = 288
b = ?

Answer 16

Hahaha, okay. But now I'm confused what to do next. Because I can't like divided or multiply b by 288 because it's a letter..

Answer 17

take square-root both sides

Answer 18

Ohhhh. So the answer is 17? Because I can't get a square root of a letter, and the square root of 288 is 16 with a bunch of numbers behind it, so I needed to round.

Answer 19

Yep!

Answer 20

Yay :D Tysm!
