hypotenuse 4 times length of perp.: find acute angle

[karan]

In a right-angled triangle the hypotenuse is four times as long as the perpendicular drawn to it from the opposite vertex, then what will be the one of acute angles?

Re: triangle

What are your thoughts?

Sketch the triangle approximately.

What can you say about sine, cosine and tan of the angle in question?
