in the diagram, ab is 6 units, bc is 30 units, and ae is 4 units. if △abe ~ △acd by the sas similarity theorem, what is ad? 16 units 20 units 24 units 28 units
Answer
Answer:
B. 20 units
Explanation:
Step1: Identify corresponding sides
Since $\triangle ABE\sim\triangle ACD$ by SAS, $\frac{AB}{AC}=\frac{AE}{AD}$.
Step2: Calculate AC
$AC = AB + BC=6 + 30=36$ units.
Step3: Set up proportion
We have $\frac{6}{36}=\frac{4}{AD}$.
Step4: Cross - multiply
$6\times AD=4\times36$.
Step5: Solve for AD
$AD=\frac{4\times36}{6}=20$ units.
