Question

Precal: 10 points if you could help me! It’s multiple choice

Answer 1

Your answer is B) 35π/18.

The size of angle x is equal to π/18, which you find by doing π/2 - 4π/9 because π/2 is the size of a right-angle in radians.

However, as this is not an available option, I believe the question is asking for the size of the angle subtended by the red arrow. You can find this by doing 2π, which is 360° in radians, minus π/18. This gives you 35π/18, which is option B.

I hope this helps!
