(a) apples

(b) oranges

(c) pears

We notice there are 3 Apples, 4 Oranges and 2 Pears, that make a total of  9.

Since the total central angles in a pie = 360° and since we have 9 sectors, so each sector will have a central angle of 360/9 = 40°. Hence:

3 Apples = 3 x 40° = 120° (a)

4 Oranges = 4 x 40° = 160° (b)

2 Pears    =  2 x 40° = 80°  (c)

PROOF: 120° + 160° + 80° = 360°

Step-by-step explanation:

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
