If the ratio of the arc length to r is 1, then the measure of is 1 radian.

The ratio of arc length to r is always equal to 1.

If the measure of is 60, then the arc length is r.

If the measure of is 1 radian, then the arc length is r.

which options are true?

If The Ratio Of The Arc Length To R Is 1 Then The Measure Of Is 1 Radian The Ratio Of Arc Length To R Is Always Equal To 1 If The Measure Of Is 60 Then The Arc class=

Sagot :

well the radian is the measure of the radius
this line measure is then ligned up to the circumference
mearuse of 1 raidan is always equal to the measure of the radius therfor the true statements are

ratio of arc legnth to r is always equal to 1

I'm not sure what 'if the measure of is'

but I think the answer is
if the measure of is 1 radis, than the arc legnth is r since r reaprensents radius

so first and third choice are correct
