Question

1 A solution set of the equation 5 sin 0+3 = 3 contains all multiples of

1) 45°
2) 90°
3) 1350
4) 180°

Answer 1

4) 180°

Explanation:

Given the function
`5\ Sin (\theta)+3=3`

-We solve for
`\theta`:

`5\ Sin(\theta)+3=3\\\\5 \ Sin (\theta)=0\\\\\therefore Sin(\theta)=0\\\\Hence, \theta=0\textdegree=180\textdegree`

Since, 0° is not in the options, we take
`\theta=180\textdegree`

-Hence, 180° is the correct answer to the set of equation.
