How can these models be used to determine 3.06−2.5

EH = HG

EH = HG

2x + 24 = 5x - 30

x = 18

EH = 60

HG = 60

Step-by-step explanation:

what is question 4 ?

you mean the 4th point in this question, or is the whole thing question 4 ?

in any case, what they want to see here is

EH = HG (because FH is the median of the triangle, so it cuts the baseline in half).

therefore we get

2x + 24 = 5x - 30

54 = 3x

x = 18

EH = 2×18 + 24 = 36 + 24 = 60

HG = 5×18 - 30 = 90 - 30 = 60

as expected - they are equal.
