Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r = = 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer:
a) m∠6 = 55 and m∠8= 55 - 20 --> m∠8= 35 x = 55
b) m∠7 = 40 and m∠9 = 140 x = 40
c) m∠8 = 46 and m∠7 = 46 x = 18
d) m∠6 = 63 and m∠7 = 27 x = 9
(just like the note says at the top each one is a different problem hence the different answer or each angle even if its the same one)
