Answer:

<h2>15</h2>

Solution,

Hypotenuse(h)= 25

Base(b)= 20

perpendicular (p)= X

Now,

Using Pythagorean theorem:

{p}^{2}  =  {h}^{2}  -  {b}^{2}  \\  {x}^{2}  =  {25}^{2}  -  {20}^{2}  \\  {x}^{2}  = 625 - 400 \\  {x}^{2}  = 225 \\ x =  \sqrt{225}  \\ x =  \sqrt{ {15}^{2} } \\ x = 15

Hope this helps...

Good luck on your assignment..

Answer:

x = 15

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 20² = 25² , that is

x² + 400 = 625 ( subtract 400 from both sides )

x² = 225 ( take the square root of both sides )

x = \sqrt{225} = 15

The sum of two numbers is 72. one number is 4 less than the other number. what are the two numbers?
-Dominant- [34]
Let 1st number be = x
Thus second number = x - 4

Now

(x) + (x - 4) = 72
2x - 4 = 72
2x = 76
x = 38

1st number is 38 thus 2nd number is (38 - 4) = 34
