Question:

Obtian the equation that can be used to solve for c

Answer:

Sin50 = 3/c

Explanation:

A triangle showing the information given has been attached below for clarity :

Using trigonometry :

AC = 3 = opposite side of angle 50°

AB = c = hypotenus

Using the sine relation of a right angled triangle :

Sin θ = opposite / hypotenus

θ = 50°

Sin 50° = 3 / c

Sin50 = 3/c

Right triangle ABC is shown. Triangle A B C is shown. Angle A C B is a right angle-example-1
