Question

Find the missing side: ​

Answer 1

c = 10.29417310909429

[c = 10.29 (rounded)]

Explanation:

In a right triangle, there is a specific method to find a missing side. The two straight edges (that make up the 90-degree corner) can be called leg a and leg b. The longer side, which is called the hypotenuse, can also be called c.

(leg / side)

The relation between these sides is that:

a² + b² = c²

This is called the Pythagorean theorem.

For your triangle, leg a is 6.6, and leg b is 7.9, and the missing side (x) will be represented as c

6.6² + 7.9² = c²

43.56 + 62.41 = c²

105.97 = c²

`√(105.97) = √(c^2)`

10.29417310909429 = c

c = 10.29417310909429

c = 10.29 (rounded)

Answer 2

10.29

Explanation:

use Pythagorean theorem

side opposite to 90 is always hypotenuse

and we know

h^2=p^2+b^2

you can put any side as perpendicular or base.
