Question

Find the value of x in the triangle shown below.
2.5
C
6.5
Choose 1 answer:

Answer 1

x = 6

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

6.5² = x² + 2.5²

42.25 = x² + 6.25 ( subtract 6.25 from both sides )

36 = x² ( take square root of both sides )

`√(36)` = x , that is

x = 6

Answer 2

`x = √(36) \\ that \: is(x = 6)`
