Question

Solve the trigonometric equation
1-2sin(theta) =2 for 0°≤(theta)≤360°

Answer 1

Answer:

theta=210⁰

Step-by-step explanation:

1-2sin(theta)=2

1-2=2sin(theta)

-1=2sin(theta)

-1/2=sin(theta)

theta=sin inverse (-1/2)

theta=210⁰

as sin(theta) is 1/2 for 30⁰ but it is -1/2 so sin is negative in 3rd quadrant and that is 210⁰
