Answer:

36:54:90

Step-by-step explanation:

you add all the parts together (2+3+5) which is 10. then you divide 180 by 10 because angles in triangle add up to 180. so 18 is one part

then you just times 18 by each part in the ratio

atroni [7]

Answer:

  • D(5, 4), E(14, 7), M(9.5, 5.5)

Step-by-step explanation:

As AD = 1/4AB and DE ║ AC, the ratio CE/CB = 1/4, or CE = 1/4CB

<u>Find the coordinates of D:</u>

  • x = 1 + 1/4(17 - 1) = 1 + 4 = 5
  • y = 5 + 1/4(1 - 5) = 5 - 1 = 4

<u>Find the coordinates of E:</u>

  • x = 13 + 1/4(17 - 13) = 13 + 1 = 14
  • y = 9 + 1/4(1 - 9) = 9 - 2 = 7

<u>Find the coordinates of the midpoint M of DE:</u>

  • x = (5 + 14)/2 = 19/2 = 9.5
  • y = (4 + 7)/2 = 11/2 = 5.5
