Answer:

7 units long

Step-by-step explanation:

We are given a right triangle ABC

  • AB = 25 units
  • BC = 24 units

We are required to determine the length of AC

  • We are going to use the Pythagoras theorem;
  • According to the theorem, if a and b are the legs of a right triangle and c is the hypotenuse, then;

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

Mumz [18]

Answer:

Firstly Substitute y=2x-5 into 5x-4y=-10

This will be 5x-4(2x-5)=10 now solve for x

5x-8x+20=-10

-3x=-30

X=10

Now sub x as 10 into the second equation y=2x-5

Y=2(10)-5

Y=15
