Given:
The right angle triangle with legs 4 units and 7 units.
To find:
The length of hypotenuse.
Solution:
Pythagoras theorem: In a right angle triangle,
Let x be the length of the hypotenuse.
Using the Pythagoras theorem for the given triangle, we get
Taking square root on both sides, we get
[∵Side length cannot be negative]
Therefore, the length of the missing side for the given right angle triangle is 8.06 units.
After putting the value of y from the second equation to the first equation, the resultant equation is .
GIven:
The equations are:
It is required to put the value of y from second equation to the first equation.
<h3>How to solve equations?</h3>The value of y from the second equation is,
Now, put this value of y in the first equation as,
Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is .
