Question

ΔRAF ~ ΔAMYIf A(F) is 10 mm, RF is 15 mm, and MY is 8 mm, AY is ___ mm.(had to censor the f, my apologies)

Answer 1

AY= 12 mm

Step by step explanation:

By using the diagram above, and proportional relationships because the triangles are congruent:

`(10)/(8)=(15)/(x)`

Solve for x:

`10x=15\cdot8`
`\begin{gathered} 10x=120 \\ x=(120)/(10) \\ x=12 \end{gathered}`

AY= 12 mm
