Answer: Answer C , Only student 2, because dilation preserve angle measures and side lengths are proportional
5a+5b because 6a-a=5a and 8b-3b=5b. 5a+5b.
Answer:
1) b 243
Sorry, I couldn't figure out the other two..
Step-by-step explanation:
Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25
Hence, angle a = 3(25) - 10 = 65°
