Answer:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.

(Root 15^2-9^2=12) (Root 12^2+16^2=20)

Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.

(Root 25^2-15^2=20)

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.

We have to find the value of ‘a’ using two different ways.

By the Pythagorean theorem,

By cross multiplication,

16(25) = a2

a2 = 400

Taking square root,

a = 20

Therefore, the length of the other side a = 20.

How do you find the value?

You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.
