Question

Help me please I’m dying

Answer 1

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

Answer 2

Answer:

$\boxed{x = 2+2\sqrt{6} ~~or~~x = 2 - 2 \sqrt{6} }$

.

Step-by-step explanation:

To find x, use pythagoras form

$c^2 = a^2 + b^2$

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

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

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

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

$x^2 - 6x = 15$

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

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

$(x - 3)^2 = 24$

$x - 2 = \pm \sqrt{24}$

$x = 2 \pm 2\sqrt{6}$

.

$x_1 = 2 + 2\sqrt{6}$

$x_2 = 2 - 2\sqrt{6}$

.

Happy to help :)
