In triangle abc, m∠c = 90°, c = 17, and a = 8, then which of the following is the measure of side b?

Step-by-step explanation:

We have been given that in triangle ABC, m∠C = 90°, c = 17, and a = 8. We are asked to find the measure of side b.

Since the measure of angle C is 90 degree, so our given triangle is a right triangle, where side c is the hypotenuse of triangle.

We will use Pythagoras theorem to solve for side b as:

Now, we will take square root of both sides of our equation.

Since length cannot be negative, therefore, the length of side b is 15.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
