PLEASE HELP

90 degrees

Step-by-step explanation:

Hello there!

The triangle shown inside of the circle is formed with the diameter.

The diameter stops at a tangent line forming three angles

y, the one inside of the triangle and the other interior angle

Remember the diameter splits the circle in half and if the diameter intersects with a tangent line then its going to form 2 right angles

so we can conclude that the measure of y is 90 degrees

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

-2 is the right
