Answer to 2/3 + 1/6 is 5/6.
NOT SIMILAR
Explanation:
Look at the bottom of the triangle, the bottom of the left one is shorter than the right making the triangles not similar.
Option C is the right answer
½(12) = 6
½(64) = 32
½(30) = 15
½(78) = 39
Y = mx + b
slope(m) = -3
(2,7)...x = 7 and y = 2
now we sub and fund b, the y int
2 = -3(7) + b
2 = -21 + b
2 + 21 = b
23 = b <== ur y int
