Give the vertices of a
triangle that is 3 times as big
as triangle abc if a(0,0), b(2,6),
and c6,4). (centered at the
origin)

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

answer is b
