What is the standard form of the equation of the circle in the graph? (x − 3)2 + (y + 1)2 = 2 (x + 3)2 + (y − 1)2 = 1 (x − 3)2 + (y + 1)2 = 1 (x + 3)2 + (y − 1)2 = 2

make sure you have version 2.50

try looking in the very back of the book : )

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm
