Answer:

$\boxed{\textbf{B). } x = -1, x = 2}$

Step-by-step explanation:

The solutions to the quadratic function are the points where its graph crosses the x-axis.

The graph crosses the axis at x = -1 and x = 2, so the answer is

$\boxed{x = -1, x = 2}$

Angles A and B are complementary and in ratio of 3:6. What is the measure of each angle

pashok25 [27]

complementary angles add up to 90°, so therefore we know that ∡A + ∡B = 90°, and also they are in a ratio of 3:6.

$\bf \cfrac{A}{B}=\cfrac{3}{6}\implies \cfrac{A}{B}=\cfrac{1}{2}\implies 2A=\boxed{B}
\\\\[-0.35em]

A+B=90\implies A+\boxed{2A}=90\implies 3A=90\\\\\\ A=\cfrac{90}{3}\implies \blacktriangleright A=30 \blacktriangleleft
\\\\[-0.35em]

2(30)=B\implies \blacktriangleright 60=B \blacktriangleleft$
