Label your sides= hypotenuse(h),opposite(o),adjacent(a) hypotenuse=longest(opposite the right angle) opposite= opposite the other angle adjacent= the other side see which sides are involved in this case it is adjacent and hypotenuse so A and H we have to use the SOHCAHTOA rule Sin=o/h Cos=a/h Tan=o/a we use cos because a and h are involved Cos(15°)=62/x rearrange the equation to find x x= 62/cos(15) put this in your calculator x= 64.12
