Question

The measurement of an angle of a right triangle is 40° and the leg opposite to this angle is 5 cm long. what is the length, in cm, of the other leg?

Answer 1

sine 40 = 5 / hypotenuse
0.64279 = 5 / hypotenuse
hypotenuse = 5 / 0.64279
hypotenuse = 7.7786
tangent (50) = opp / adj
tangent (50) = opposite / 5
1.1918 * 5 =  opposite
opposite side = 5.959
