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

Answer:

AY= 12 mm

Step by step explanation:

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

$\frac{10}{8}=\frac{15}{x}$

Solve for x:

$10x=15\cdot8$$\begin{gathered} 10x=120 \\ x=\frac{120}{10} \\ x=12 \end{gathered}$

AY= 12 mm
