How do I do this problem?

14.9m

Step-by-step explanation:

Say that the centre point is O, the letter to make it easier to explain.

The angle DOB is equal to the angle AOE because they're vertically opposite

We also know that angle DOB = 52 + 90 = 142, so angle AOE = 142

To work out the length of the segment, it would be to find the circumference and multiply with the angle over 360:

πd ×

(where d = diameter)

we know that the diameter is 12m so we can input this:

12π × = 14.87020523

to the nearest tenth = 14.9m

answer: 25 is the correct answer

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
