Answer:

x = 36°

Step-by-step explanation:

interior angle of regular pentagon: 180 x (5-2) /5 = 540 / 5 = 108

∠C = 108

CD = CB ∠CDB = ∠CBD = (180 - ∠C) /2

x = (180 - 108) / 2 = 36°

Write x squared + 2x-8 in the form (x + m) squared + n where m and n are integers.

skelet666 [1.2K]

Let F(x) = x^2 + 2x -8

Adding 1 and - 1 at equation

F(x) = x^2 + 2x + 1 - 1 -8

Rewrinting the first 1 = 1^2

F(x) = x^2 + 2x + 1^2 - 1 - 8

Now look:

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

Then,

F(x) = (x + 1)^2 -1 -8

F(x) = (x + 1)^2 -9

This is the answer !

If us to want.

(x + 1)^2 -9 = ( x+1)^2 - 3^2

= ( x+ 1 -3).(x +1 +3)

= ( x - 2).(x +4)

levacccp [35]

Answer:

Yes, the right angle is angle C.

Step-by-step explanation:

The given triangle has vertices at A(–2, 3), B(–3, –6), and C(2, –1).

Recall the slope formula;

$m=\frac{y_2-y_1}{x_2-x_1}$
