#22 and #25 = correct
#21 use the distance formula:
d = square root of [(x2-x1)^2+(y2-y1)^2]
where the coordinates are (x1,y1) and (x2,y2)
For your problem d = 5.... now you plug all the numbers in that equation and solve for y2.
Need help with these--
21. Find the possible values of a, of the distance between the points is 5, and the coordinates are (1, 1) and (4,a)
22. The Pythagorean Theorem works only for _______ triangles.
Right?
25. Three sides of a triangle are 2, 4, and 8. The two smallest sides of a similar triangle are 4 and 8. What is the measure of the missing side?
16?
Thanks
