Major arc cbd measures 300°.

which is the radian measure of its corresponding central angle?

Step-by-step explanation:

I believe you meant, "Major arc CBD corresponds to a central angle of 300°.  Which radian measure corresponds to this 300° central angle?  Sounds as though there were answer choices; would you please list all given answer choices next time.

300° corresponds to what angle measured in radians?

Multiply 300° by the conversion factor

    π

 180°

This results in:

300°         π          5π

* =

   1           180°        3

The radian measure corresponding to 300° is (5/3)π.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
