Find x and decide if that side (with the x) is an Altitude
irga5000 [103]

Answer:

  1. b = 15
  2. c = 51
  3. c = 100
  4. b = 25.75

Step-by-step explanation:

Using the Pythagoras theorem equation:

c^{2}=a^{2}+b^{2}

Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.

1) Here c = 17, a = 8 and b = ?

Then, using the above equation we can find the side b.

17^{2}=8^{2}+b^{2}

b=\sqrt{225}

b=15

2) Here a = 24, b = 45 and c = ?  

c=\sqrt{24^{2}+45^{2}}

c=51

3)  Here a = 28, b = 96 and c = ?

c=\sqrt{28^{2}+96^{2}}    

c=100

4)  Here a = 17, b = ? and c = 28

b=\sqrt{28^{2}-11^{2}}  

b=25.75

Just in the 4 case x is an altitude.

I hope it helps you!
