Question

Find the length of the missing side. The triangle is not drawn to scale.

Answer 1

pythag right?

Answer 2

yes i think

Answer 3

you give me your best effort and let me see if you are on the right track :)

Answer 4

so would i take 17^2+15^2?

Answer 5

close

recall, a^2 + b^2 = c^2

we have b and c

a^2 + 15^2 = 17^2

a^2 = 17^2 - 15^2

a = sqrt(17^2 - 15^2)

Answer 6

alright so it would be the sqrtof 289-225?

Answer 7

that looks to be about right yes.

17
17
170
70
49
289 ... 17^2 pans out

Answer 8

ok then waht i get for that will be the missing side then?

Answer 9

then i would try to simplify it; what is 289-225?

Answer 10

yes, the simplification would represent the missing side

Answer 11

so 289-225=64 then the sqrt of 64?

Answer 12

the sqrt of 64 is 8

Answer 13

then the missing side is 8 :)
