Answer:

Step-by-step explanation:
The three interior angles in a triangle will always add up to 180°.
Therefore

Answer:
15 maybe?
Step-by-step explanation:
42 - 14 = 28
18 - 5 = 13
28 - 13 = 15
subtract the 14 because it says it is in neither.
Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.
Subtract 13 from the 28 because those 13 are in math and wont be in science also.

Option C.
Answer:

Step-by-step explanation:
From the graph in the attachment Y has coordinates:Y(3,2)
The transformation rule for a dilation with a scale factor k about the origin is:

In this case we have 
We substitute the coordinates and
to get:

This simplifies to:

The first choice is correct.
