Question

choose a method to apply to each problem and solve for all of the variables leave your answer in simplest form

Answer 1

Trig will be used to solve this.

x =

Step-by-step explanation

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

For this question,

Hypotenuse = x

Opposite = ?

Adjacent = 13

Angle = 42°

Trignometric ratios enable us to say CAH mean

Cos 42° = (Adj/Hyp)

Cos 42° = (13/x)

Cos 42° = 0.7431

Cos 42° = (13/x)

0.7431 = (13/x)

Cross multiply

x = (13/0.7431)

x = 17.5 units
