We can solve this question in 2 ways: either using
degrees or converting the degrees into
radians.
Since, the question says degrees itself and there is no specification of using radians only, so I have solved it using degrees itself.
Part (a):
Perimeter of sector ORS = 2*Radius + Arc RS = 2*21 +

Part (b):
Area of sector ORS =

Area of sector POQ =

Thus, area of shaded region
= Area of sector ORS - Area of sector POQ
=
This question doesn’t really make sense- is it multiple choice, if so what are the options? A can be anything as long as it’s the same?
No their not they have four sides but their not
Answer:
The answer is C
Step-by-step explanation:
Answer:
y + 4 = -2(x - 3)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h). Substitute -2 for k and 3 for h, as well as -2 for m:
y + 4 = -2(x - 3).
