Step-by-step explanation:
Answer:

Step-by-step explanation:
AD = BD (CD bisects AB means that it divides the line into two equal parts)
So,
AD = BD = AB/2
So,
AD = 3/2
AD = 1.5
<u><em>Now, Finding AC using Pythagorean Theorem:</em></u>

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)



Taking sqrt on both sides

1 (5) = 5
7/10(5/1) = 35/10
Simplify.
35/10 = 3 5/10 = 3 1/2
5 + 3 1/2 = 8 1/2
