Step-by-step explanation:

tan x = 3/4

Tangent is opposite over adjacent, so draw a right triangle with angle x where the opposite side is 3 and the adjacent side is 4.

Use Pythagorean theorem to find the hypotenuse:

c² = 3² + 4²

c² = 25

c = 5

Sine is opposite over hypotenuse, so:

sin x = 3/5

If EG=67, then EF=? There is a picture below

ikadub [295]

If EG=67 we have (3x+7)+(5x-4)=67
let's simplify
$67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\ \frac{64}{8} = x \\ 8 = x$
now we know x is 8 we can use this to find EF
since EF=3x+7
$3(8) + 7 = 24 + 7 = 31$
so we have EF is 31!
