<span>x^2 + y^2 – x – 2y – 11/4 = 0
x^2 - x + y^2 - 2y = 11/4
Using completing the square method:
x^2 - x + 1/4 + y^2 - 2y + 1 = 11/4 + 1 + 1/4
(x - 1/2)^2 + (y - 1)^2 = 4

Straight lines are equal to 180, therefore 180-56 gives you 124 for the opposite angle to x. Adding 56, 124 and 87 gives you 267. 360-267=93
Answer:
C.
Step-by-step explanation:
The expression defines the given series for seven terms, i don't understand the question but i do know the sum which you should know to
