Answer 1

For the first triangle, x equals 22cm.

Here's how:-

x is the altitude or height of the triangle. To find it, we can use the Pythagoras theorem:-

`altitude^(2) + base^(2) = hypotenuse^(2)`

The base is 120cm and the hypotenuse is 122cm

Putting this in the equation, we get:-

`altitude^(2) + 120^(2) = 122^(2)`

`altitude^(2) = 122^(2)- 120^(2)`

`altitude^(2) = 14884 - 14400`

`altitude^(2)` = 484

altitude =
`√(484)`

altitude = 22cm

So, x = 22cm
