Question

Find the missing side of a triangle.

Answer 1

@SolomonZelman

Answer 2

From trigonometry we know
tan (22 degrees) = x / 26

Answer 3

I know that we have the adjacent (26) and the opposite sides (x) so we can find the tangent of 22 degrees.

1) tan(22) = 0.4
2) 26/x = 0.4
3) 26 = 0.4x
4) x = 65

Answer 4

did i make any mistakes @wolf1728

Answer 5

Yes, x = 65 is incorrect.

Answer 6

can you explain to me where i made the mistake?

Answer 7

i think i know how:
i mixed up opp. and adj.

Answer 8

You divided when you should have multiplied.
I started with
tan (22 degrees) = x / 26

.40403 = x / 26
x = 26*.40403
x=10.50478

You set it up as
x= 26/.04043
x= 64.35 which it DOESN'T

Answer 9

i got it! thanks!
