Question

If m 12 years ago

Answer 1

m or n?
cuz it has n

Answer 2

It's n in the diagram, but the question says m angle R= 37. I think that m stands for measure.

Answer 5

well do you know the property of the angles subtended by a chord of a circle?

Answer 6

No. I don't think I do :/

Answer 7

Angle O is the central angle and angle R is an inscribed angle, so their measures will be different.

Answer 8

When the intercepted arc is minor, which in this case, it is, the inscribed angle is exactly half the measure of the central angle.

Since the measure of angle R is 37 degrees, angle O must be twice the measure of R.

Answer 9

So how do I start working it out? With the Pythagorean theorem?

Answer 10

Oh no I need two values at least for that, right? Ugh :/

Answer 11

Ohh okay. So then that means O is 74.

Answer 12

So is it the same rule for this problem? 48*2
