Answer:
AB = AD = 22 units
Explanation:
1- solving for r:
We are given that:
AD is congruent to AB
This means that:
AD = AB
2r + 8 = 5r - 13
5r - 2r = 8 + 13
3r = 21
r = 21/3
r = 7
2- getting the value of AB:
Since we calculated the value of r, we can simply substitute in the equation to get AB as follows:
AB = AD = 5(7)-13 = 2(7)+8 = 22 units

Answer:
x = 4.1 cm
Step-by-step explanation:
15.6 / 2 = 7.8
x^2 = 8.8^2 - 7.8^2
x^2 = 77.44 - 60.84
x^2 = 16.6
x = 4.1
