Question

17. B is the midpoint of ac and D is the midpoint of ce. Solve for x, given BD = 3x + 5 and AE = 4x + 20.

Answer 1

you just need to use the scaling ratio

triangle CBD and ACE are similar so the scaling factor is 1/2

so then BD = 1/2 AE

so

\[ 3x + 5 = \frac{1}{2}\times(4x + 20)\]

just solve for x

Answer 2
