The vertical is 12

The horizontal is 12 / tan(47).

Good work.

Tangent is rise over run or slope or first derivative.]]>

where right angle is at the bottom right of trangle and hypotenuse is facing left, y = base and 12

= opposite to hypotonuse (can't seem to upload a picture)

Tan47 = 12/y

y x Tan47 = 12

y = 12/Tan47

y = 11.19018103

y = 11.2 (rounded to 1d.p.)

(please tell me if you work it out otherwise)

I know it's quite vague but is there any way i could extend my trigonometry studies?
