Since angle HBC is a right angle, therefore it's 90 degree. So to prove that ΔABC (pre-image) and ΔIBH (image) use the same amount of fabric, point B should be rotated 90 degree clockwise. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
It would be 30 if the angles are interior or exterior.
Hi there!
Use slope formula to solve for the slope of the line:
Plug in points into the equation. We can use the points (0, -10) and (25, -5):
Answer:
-10 -12 -14 -16 -18 -20 -22 -24 -26 -28
