What is the length of the side a ?<br><br> A=
vodka [1.7K]

Answer:

a = 5

Step-by-step explanation:

Notice that \triangle CDB is a right triangle where its hypotenuse is \overline{CB}. We can also see that a = CB. For this we must use the Pythagorean Theorem.

Recall:

The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.

We can see that CD = 3 and DB = 4

a = \sqrt{CD^2 +DB^2} \\ a = \sqrt{3^2 +4^2} \\ a = \sqrt{9 +16} \\ a = \sqrt{25} \\ a = 5
