Question

Find the missing side: ​

Answer 1

Answer:

c = 10.29417310909429  

[c = 10.29  (rounded)]

Step-by-step 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

$\sqrt{105.97} = \sqrt{c^2}$

10.29417310909429 = c

c = 10.29417310909429

c = 10.29  (rounded)

Answer 2

Answer:

10.29

Step-by-step 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.
