Complete the solution of the equation. Find the
value of y when x equals 15.
-x + 2y = -1

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

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

i hope i you.
