Question

Use the tangent to find the length of side A C. Express your answer to the nearest tenth. 27° 7.0 The length of side AC is approximately units.

Answer 1

From the basic knowledge of trignometry,

tan 27 = x /7.0

cross-multiply

x = 7.0 x tan 27

x = 7.0 x 0.5095

x = 3.5665 = 3.6 units ( nearest tenth)
