Given: ∠1 = ∠2 If AB = 10, AC = 6, and BC = 6, find AD:
5
10
15

Answer: AD = 5
because AB equals 10, logically we assume AD equals 5, hopefully this helps you.
Answer:
AD=5
Step-by-step explanation:
We are given that
[tex]\angle 1=\angle 2[/tex]
AB=10, AC=6 BC=6
We have to find the value of AD.
Let AD=x
BD=AB-AD
BD=10-x
By angle bisector theorem
[tex]\frac{AC}{AD}=\frac{BC}{BD}[/tex]
Substitute the values then we get
[tex]\frac{6}{x}=\frac{6}{10-x}[/tex]
[tex]\frac{10-x}{x}=\frac{6}{6}[/tex]
[tex]\frac{10-x}{x}=1[/tex]
[tex]10-x=x[/tex]
[tex]x+x=10[/tex]
[tex]2x=10[/tex]
[tex]x=\frac{10}{2}=5[/tex]
Hence, the value of AD=5 units
