Which of the following is not equal to sin⁡(-230°)?
sin(130°)
-sin(-50°)
sin(50°)
sin(-50°)

sin(-50°) is not equal to sin(-230°)

Step-by-step explanation:

You will be required to use a scientific calculator for this.

Step 1 : Find out the value of sin(-230°)

sin(-230°) = 0.766

Step 2 : Find out all the other values and see if they are 0.766 or not.

sin(130°) = 0.766 (It is equal to sin(-230°))

-sin(-50°) = 0.766 (It is equal to sin(-230°))

sin(50°) = 0.766 (It is equal to sin(-230°))

sin(-50°) = -0.766 (It is not equal to sin(-230°))

∠cbe and ∠deb are same-side interior angles.
