Question

What is the value of x to the nearest tenth?

(Please explain how to do this. I can't remember)

Answer 1

you have 2 legs and the angle, the angle is opposite to the leg,
so we can write TAN of the angle

tan(43°)= (opposite leg)/(adjacent leg)
tan(43°)= x/12
x=12*tan(43°)≈ 11.2

Answer 2

`\tan(\Theta) = \frac{\text{opp}}{\text{adj}}`


`\tan(43) = (x)/(12)`


`x = \tan(43) * 12`


`x = 11.2`
