Solve for x, correct to one decimal place. It`s a right angle triangle. The height for the triangle is 4 cm with a 48° angle. The bottom of the triangle is an x. I got the answer 3.3 cm, is this correct? Any help would be appreciated. Thanks!

  2. Hello John,
    I was thinking of doing 4tan48° on my calculator, and the answer i got was 4.4 cm, but i wasn't sure if this was correct or not. Is this right? Thank you.
