The legs of a right triangle are lengths x and x√3. The cosine of the smallest angle of the triangle is _____.
A. 1/2
B. √3
C. (√3)/2
D. 2√3
We know that it has to be a 30-60-90 triangle based on the info. The cosine of the smallest angle, which is 30 degrees is adjacent divided by hypotenuse, or \(\frac{\sqrt{3}}{2}\) or (C). The \(2x\) came from across the 90 degree angle.
Thank you!
