Question

4. In a right triangle with one angle measuring 70 degrees, the leg opposite the 70 degree angle is 12 cm.What is the length of the leg adjacent to the 70 degree angle?

Answer 1

We want to find the value of x.

Since this is a right triangle, we can use trig functions.

We know the opposite side from 70 degrees and we want to find the adjacents side, so we will use tangent

tan 70 = opp side /adj side

tan 70 = 12 /x

x tan 70 = 12

x = 12 / tan 70

x=4.36764
