AB = 5.2

Answer 2

Step-by-step explanation:

Here,

Triangle ADC and triangle ABD are similar triangle as they are similar by A.A.A axiom.

now, as they are similar their sides are proportional to eachother,

CD/BD : AB/AC : AD/AD

4.3/4 : AB/5.6 : AD/AD.

Taking 1st and srcond ratios we get,

4.3/4=AB/5.6

or, 4AB = 5.6×4.3 (cross multiplication)

Therefore, the measure of AB is 6.02 or 6.
