Answer:

AC=[tex]\sqrt{15\\[/tex]

Step-by-step explanation:

AC is the base, BC is the hypotenuse, so the side length is AB.

We are given that AC=7 units, and BC is equal to 8.

Thus we have 8^2-7^2=(AB)^2

64-49=(AC)^2

15=(AC)^2

AC=[tex]\sqrt{15\\[/tex]

The required length of the AB = √15.

Triangle ABC is a right triangle. If AC =7 and BC=8, AB is to be determined.


What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

⇒ Pythagorean theorem for Triangle ABC
⇒BC² = AB²+AC²
⇒   8² =  AB² + 7²
⇒ AC² = 64 - 49
⇒ AC = √15

Thus, the required length of the AB = √15.
