Question

A right triangle has an angle that measures 55 degrees. The leg adjacent to this angle has a length of 43 cm. What is the length of the other leg of the triangle? Round to the nearest tenth.

Answer 1

tan55 = x/43
x = tan(55) * 43
x = 61.4 cm

Answer 2

tan (55) = opposite / 43
opposite = 43 * tan (55)
opposite = 43 * 1.4281
opposite = 61.4083
