anonymous · Answer

Use Tan 60 = Perpendicular/Base

anonymous · Answer

Right angled triangle.

Base = 4m

Angle with ground = 60 degrees

Height of top of ladder is found by

tan = Opposite/Adjacent

tan (60) = Opposite/4

Opposite = 4 + tan(60) = 6.9m

This is the height of the top of the ladder above ground.

Hope this helps.

Tan 60 = Perp/4. Solve for Perpendicular

@victoria.stearns Opposite = 4 multiplied by tan, not added to tan...

anonymous · Answer

So the answer would be 4 x 60?

anonymous · Answer

4 x Tan 60. 60 and Tan 60 are different things

I dont get what tan is tbh. is that short for something?

This website is really helpful http://www.mathsisfun.com/sine-cosine-tangent.html

It's a trignometric ratio. Tan of any angle is equal to Perpendicular/Base with respect to that angle.
