The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
Answer:
210°
Step-by-step explanation:
Given
sinΘ = -
Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is
Θ = ( ) = 30° ← related acute angle
Thus the required angle in the third quadrant is
Θ = 180° + 30° = 210°
