To find the length of line cf, I first created a square and labeled the vertices a b c d. From here you know the triangle shares the vertice b. I used the lines on the square to add point e. The distance between a and e was 2, leaving us with a distance of 4 from a to b.. I used the 4 to find the missing height. knowing that the total area was 20, the height had to be 10. I extended side cb of the triangle and made a point f. The extra part measured 4 units because the side of the square was 6, so to get 10 I needed 4 more units. I have attached a picture showing this.
62,900
21,000
126,300
856,700
Note that since 360 is a multiple of 120, 360 is the LCM of 120 and 360 - it's 360*1 and 120*3.
Answer:4,000
Step-by-step explanation:you take 4 times ten and add two zeros
D is the answer because 13 goes into 5 twice and 3 Is left over multiply that by two to get 6/10 than that it's equivalent to .6 so it is 2.6
