Question

You measure an obtuse angle on a protractor. If neither of the rays of the angle points at 0° or 180°, where could they point? Give the two points using degrees and explain why you chose those points. I need this fast i'll give you Brainliest if you answer this correctly.

Answer 1

Answer:

Measuring obtuse angles (between 90 and 180 degrees) works exactly the

same way. It may be that some protractors have only one scale, with

zero on both ends and 90 in the middle. If so, then you'll read a

number between 0 and 90, and you'll need to subtract it from 180 to

get the measure of the obtuse angle. For instance, if you read 45, the

angle is really

180 - 45 = 135 degrees

A reflex angle is the "outside" of an acute or obtuse angle. Use the

protractor to read the measure of the "inside" of the angle. Then

subtract from 360 to get the measure of the reflex angle. If the

inside is the same obtuse angle we just measured, then the measure of

the outside is

360 = 135 = 225 degrees

Answer 2

Answer:

The measure of ∠BFC is 90.

I think it is a good time
