Question

there is a right triangle. the hypotinuse lenghth is 13 the opposite side length is 12 what is the adjacent side lenth

Answer 1

5

Answer 2

169 - 144 = 25 = 5^2

Answer 3

do you guys knew about tan, sin, cos i have to use that to get the answer

Answer 4

(13)^2 = (12)^2 + x^2
169 = 144 +x^2
169-144 = x^2
25 = x^2
5 =x

Answer 5

is that using one of those three things

Answer 6

nope its simply using pythagoras theorem

Answer 7

Look, \[\sin(x) = 12/13\]

Answer 8

the adjacent side is \[13 * \cos(x) \]

Answer 9

and pythagoras gives \[ \sin^2(x) + \cos^2(x) = 1 \]

Answer 10

why to include cos and sin when we can directly get the answer?

Answer 11

so i guess you could say that, but its really unnnecessary

Answer 12

my teacher showed us these three things today so we have to use t for our hw

Answer 13

There is no need for the vocabulary of trigonometry to enter this problem.

Answer 14

oo really
