Question

Help me please I’m dying

Answer 1

x is 90 i think because it shows you the right angle

Answer 2

`\boxed{x = 2+2√(6) ~~or~~x = 2 - 2 √(6) }`

.

Explanation:

To find x, use pythagoras form

`c^2 = a^2 + b^2`

`(x + 4)^2 = x^2 + (x + 1)^2`

`x^2 + 8x + 16 = x^2 + x^2 + 2x + 1`

`2x^2 + 2x + 1 - x^2 - 8x - 16 = 0`

`x^2 - 6x - 15 = 0`

`x^2 - 6x = 15`

`(x - 3)^2 - 9 = 15`

`(x - 3)^2 = 15 + 9`

`(x - 3)^2 = 24`

`x - 2 = \pm √(24)`

`x = 2 \pm 2√(6)`

.

`x_1 = 2 + 2√(6)`

`x_2 = 2 - 2√(6)`

.

Happy to help :)
