Points J and K are midpoints of the sides of triangle FGH. What is the value of y?

The answer 

the complement of the question is 

What is the value of y?

7
<span>8

According to the image, HKJ and FGH are similar, we can apply the theorem of thales
since GK and GF are parallels, so 

HK / HF = HJ / HG = KJ / GF and as we see on the figure, HK = HF /2, this implies  2HK =HF

HK / 2HK =  KJ / GF  it is equivalent to   1/2 = 2y+5 / 5y +3 

likewise, equivalent to  5y +3  = 4y +10, 5y-4y = 10-3, and y = 7


so the answer is 7

sweet [91]

Step-by-step explanation:

Daquan's age = x

Juan's age = x

Phillipa's age = x + 3

x + x + x + 3 = 36

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 33 ÷ 3

x = 11

the twins are 11 years old
