Answer:

A. is not true

Step-by-step explanation:

$\angle{BCA}$ appears to be acute, and $\angle{BCD}$ appears to be its obtuse supplement.

Just to be sure the diagram isn't lying to you, set this up:

4x + 9 + (9x - 11) = 180

13x - 2 = 180

13x = 182

x = 14

$m\angle{BCA}=65^\circ\\m\angle{BCD}=115^\circ$

Those two angles are <u>not</u> congruent.

Blababa [14]

Answer:

(0,-5) and (-4,3)

Step-by-step explanation:

The given equations are

$\left \{ {{x^2+y^2=25} \atop {2x+y=-5}} \right.$

Make y the subject in the second equation;

$y=-2x-5$

Substitute into the first equation;

$x^2+(-2x-5)^2=25$

Expand:

$x^2+4x^2+20x+25=25$

$x^2+4x^2+20x+25-25=0$

$5x^2+20x=0$

$5x(x+4)=0$

$\Rightarrow x=0,x=-4$

When x=0,

$y=-2(0)-5=-5$

This gives; (0,-5)

When x=-4

$y=-2(-4)-5=3$

This gives (-4,3)
