Answer:

The correct answer is option C

They are complementary angles

Step-by-step explanation:

From the figure we can see two angles <ABC and <LMN,

To find the correct option

From figure we get,

m<ABC = 20°° and m<LMN = 70°

m<ABC + m<LMN = 20 + 70 = 90°

Therefore <ABC and <LMN are complementary angles

The correct answer is option C

They are complementary angles

The inequality of the graph

fiasKO [112]

Answer:

$\displaystyle y > 4x - 2$

Step-by-step explanation:

Starting from the y-intercept of $\displaystyle [0, -2],$ you do $\displaystyle \frac{rise}{run}$ by either moving four blocks south over one block west or four blocks north over one block east [west and south are negatives]. Next, we have to determine the types of inequality symbols that are suitable for this graph, which will be less than and greater than since this is a dashed line graph. We then use the zero-interval test [test point (0, 0)] to ensure whether we shade the opposite portion [portion that does not contain the origin] or the portion that DOES contain the origin. At this step, we must verify the inequalities as false or true:
