Since this is a 30-60-90 triangle, the sides are in this proportion- Shortest side (opposite of 30 degree angle)-x (v) Longest side (opposite of 90 degree angle)-2x Medium Side (opposite of 60 degree angle)- x(square root of 3) So 23 is in the 2x proportion. x is v so solve for v like this- 23=2v Divide 2. v=11.5 Since v is x and x(square root of 3) is u, solve- 11.5*square root of 3 So- v=11.5 u=11.5(square root of 3) Yes, you are correct. I just put it in decimal form. :)
