Answer:
Hi there!
The correct answer is:
a. 27831.05
Step-by-step explanation:
Since they gave you the equation for the line of best fit: y = 1.9x + 21
a. solve for x: 52900= 1.9x + 21
minus 21 on both sides to get 1.9x = 52879
then divide 1.9 on both sides to get x= 27831.05
This is a pythagorean theorem problem
When solving for the sides of a right triangle... a^2 + b^2 = c^2
Therefore, 7^2 + b^2 = 25^2
b^2 = 25^2 - 7^2 = 576
b = sqrt(576) = 24
Answer: A 24
The answer is A. more than one, because you can create one, but then you can move the angles around. So if the angles in order go 10°, 80°, 90°, you could change the order to 90°, 10°, 80°, or something. I hope this helps!
