Question

Change 7/10 pi radians to degree measure

Answer 1

Answer:

7pi/10 radians is 126º

Step-by-step explanation:

We can use a rule of three to solve this question.

An entire lap on the circle is 360º = 2pi rad.

How many degrees are 7pi/10 rad = 0.7pi rad?

360º - 2pi rad

xº - 0.7pi rad

$2\pix = 360*0.7\pi$

$x = \frac{360*0.7\pi}{2\pi}$

$x = 126$

7pi/10 radians is 126º
