Question

Can you explain how to do this?!

Answer 1

you mean tangent?

Answer 2

tan(angle)

Answer 3

use tangent

Answer 4

or you can find hypotenuse and use pythagoreans

Answer 5

no.. use tangent or cotangent \[\Large \tan(63^{\circ})=\frac{14}{x} \]

if I made a mistake, someone correct me

Answer 6

^ that's correct

Answer 7

\[H=14\div \tan 63\] find H...

Answer 8

\[\LARGE H\approx 7.13\]

Answer 9

So is the answer 7.1? How do you know to do this? I don't get it

Answer 10

They are correct! :)) By using the tangent. :))

Answer 11

My bad. i thought 14 is hypotenuse. kill me,

Answer 12

\[\Large \tan x=\frac{\sin x}{\cos x}\]

\[\Large \tan x=\frac{14}{H}\Longrightarrow \frac{\sin x}{\cos x}=\frac{14}{H}\]

use cross multiply and you'll get...

\[\Large {H\cdot \sin x}={14\cdot \cos x}\] divide both sides by sin x ...

\[\Large H=\frac{14\cdot \cos 63^{\circ}}{\sin 63^{\circ}}\]

now use calculator .. and you'll get the result..

\[\LARGE H\approx 7.13\]
