Answer:
12 : 15 : 10
Step-by-step explanation:
Let A = 4x, the B = 5x
Let B = 3y, then C = 2y
B = 5x = 3y, so y = (5/3)x
Let x = 3t, so y = 5t
Then A = 4x = 4(3t) = 12t
B = 5x = 5(3t) = 15t
C = 2y = 2(5t) = 10t
so A : B : C = 12t : 15t : 10t = 12 : 15 : 10
10 x 42= 420 6 x 3=18 420-18=402 402 + 3= 405 Answer:405
Sample answer from Edmentum
Answer:
D = (9.6,0). AC is horizontal with y=0 at all points on AC. Also, because BD is an altitude, it forms a right angle with AC, so BD is a vertical line. For all points on BD, x= 9.6.
Hope this helps, have a good day (:
