Question

The degree measure of angle a is 135°. which expression below is equivalent to the radian measure of angle a?

Answer 1

It is given that $\angle a=135^{\circ}$.

Now, know that in 180 degrees there are $\pi$ radians. This can be written as:

$180^{\circ}=\pi$ radians

$\therefore 1^{\circ}=\frac{\pi}{180}$ radians (dividing both sides by 180)

Thus, to find the measure of the given angle of $135^{\circ}$ in radians, we will have to multiply the above equation by 135. Thus, we get:

$135^{\circ}=\frac{\pi}{180}\times 135$ radians

$135^{\circ}\approx2.356$ radians

Thus, equivalent to the radian measure of angle a is 2.356

Answer 2

Answer:

I know this an Odsseyware question. From what I've seen my educated guess would be 135/180. It's more than likely that it is at least ?/180. I saw one answer saying that 135pi/180 was incorrect, but of course there's no telling who is or isn't right when practically no one is able to figure the question out alone.

Good luck to you hardworking students.
