Question (in need of help)

Answer 1

the top angle is 11 and the angle on the left is 9 so the X will be rounded to the nearest hundreth since it's the biggest angle so 11×9=109 so yea I THINK its 100 since it's rounding

Answer 2

Required Answer:-

This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.

By Pythagoras theoram,

`{p}^(2) + {b}^(2) = {h}^(2)`

where p is the perpendicular, b is the base and h is the hypotenuse.

Plugging the values,

`{9}^(2) + {11}^(2) = {h}^(2)`

Then,

`h = \sqrt{ {9}^(2) + {11}^(2) }`

`h = 14.12(approx.)`

Hence:-

The x of the right angled ∆ = 14.12
