Question

If segment AG is 4x, segment GI is 3x + 5, and segment AI is 48, what is the length of segment GI to the nearest whole number?

Answer 1

GI is 21

Explanation:

Mathematically, from the question;

AI = AG + GI

48 = 3x + 5 + 4x

48 = 8x + 5

48-5 = 8x

8x = 43

x = 43/8

GI is 3x + 5.

= 3(43/8) + 5

= 16.125 + 5 = 21.125

which is 21 to the nearest whole number
