How do you find the reference angle for the angle 63 degrees?

1 Answer

If you are asking for the measure in "circular system"......it is color(green)(((7pi) / 20)^c)

Explanation:

we know,
180^@= pi radian

or, 1 ^@=pi/180 radian.

or,63 ^@ =((cancel(63)^color(brown)7) *( pi)) / (cancel(180) ^color(brown)(20) radian

=color(green)( ((7pi) / 20)^c)
