C) The 2 triangles are similar , then we can write:
5x/45 = 20/36 . Cross multiplication:
5x*36 = 45*20
180x = 900 and x = 900/180 , x = 5 (and 5x = 25)
d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:
8x = 60 and x = 60/8 , x = 7.5
y = mx + b
slope(m) = -4/5
(10,5)...x = 10 and y = 5
now sub into the formula and find b, the y int
5 = -4/5(10) + b
5 = -40/5 + b
5 = -8 + b
5 + 8 = b
13 = b
so ur perpendicular equation is : y = -4/5x + 13 <===

Answer:
The car traveled 740.52 miles
Step-by-step explanation:
The only thing you need to do in this problem is to multiply the hours by the rate (mph).
3.6 × 205.7 = 740.52
