In right triangle abc, angle c is a right angle, ab is 25 units long, and bc is 24 units long. what is the lenght of ac?

7 units long

Step-by-step explanation:

We are given a right triangle ABC

We are required to determine the length of AC

a² + b² = c²

In this case;

AB is the hypotenuse and BC is one of the legs of the triangle;

Therefore;

AB² = BC²+AC²

Rearranging the formula;

AC² = AB² - BC²

       = 25² - 24²

       = 625 - 576

       = 49

AC = √49

     = 7

Thus, AC is 7 units long

21

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
