Question

7. The figure below contains two right triangles. Din Which statements are TRUE? Select TWO that apply A) AD= 12 17 B) AC # 14.25 ft D] BC 45.83 ft

Answer 1

$\begin{gathered} AD^2+5^2=13^2\text{ (Pythogrean rule)} \\ \Rightarrow AD=\sqrt[]{169-25}=\sqrt[]{144}=12ft \\ \\ \text{Option A} \end{gathered}$$\begin{gathered} BC^2=5^2+3^2=25+9=34 \\ BC=\sqrt[]{34} \\ \Rightarrow BC\approx5.83ft \\ \\ \text{Option D} \end{gathered}$

So options A and D are true
