The side a measures units and the side x measures
units.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.
We use the triangle with sides 7 and 2 as we do not know the length of side x in the first triangle
In the given triangle, the hypotenuse is the side that is represented by a. The other sides on the triangle measure 7 and 2 units.
Step 2:
So according to the Pythagorean theorem,
Step 3:
Now for the first triangle, the same Pythagorean theorem can be used.
The length of the hypotenuse is and the sides of the triangle are 5 and x.
So
28 can be written as 7 times 4 and the root of 4 is 2 so .
The length of x is
