[tex]x 1,2 = -(-8) \sqrt( (-8)x^{2} -4 X1 X (-180))/ 2X1[/tex]Answer:

Large angle+ small angle=180 because straight line = 180 degrees.

(x^2 - 11x)+(3x)=180

= x^2 - 11x + 3x=180

= x^2-8x=180

= Simplify: x^2 - 8x - 180 = 0

=

Answer:

x = 18

Step-by-step explanation:

Let's find x :-

[tex] {x}^{2} - 11 + 3 = 180^{o} [/tex]

[tex] {x}^{2} - 8x = 180[/tex]

[tex] {x}^{2} = 8x - 180 = 0[/tex]

[tex](x - 18)(x + 10)[/tex]

[tex]x = 18[/tex]
