Question

Which equation can be used to solve for c? Triangle A B C is shown. Angle A C B is 90 degrees and angle A B C is 35 degrees. The length of C B is 5 inches, the length of A C is b, and the length of B A is c. c = (5)cos(35o) c = StartFraction 5 Over cosine (35 degrees) EndFraction c = (5)sin(35o) c = StartFraction 5 Over sine (35 degrees) EndFraction

Answer 1

B is your correct answer.

Explanation:

Answer 2

The correct option is B)
`c=(5)/(\cos35^0)`.

Explanation:

Consider the provided information.

Angle A C B is 90 degrees and angle A B C is 35 degrees.

The required figure is shown below:

We need to find the value of c.

Use the trigonometric function:
`\cos\theta=(Adjacent)/(Hypotenuse)`

`\cos35^0=(5)/(c)`

`c=(5)/(\cos35^0)`

Hence, the correct option is B)
`c=(5)/(\cos35^0)`.
