Which equation represents a vertical line?

1 answer:

4 0

The answer is x=12
y=-x would be a negative slope
y=12 would be a horizontal line because you can put any point on that line and it's y would always be 12 but it's x coordinate can be anything else
x=y is a positive slope
x=12 is a vertical line because you can put any point on that line and it's x coordinate would always be 12 but its y coordinate can be anything else

Answer:

x = 76.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side / adj side

tan 70 = x/28

28 tan 70 = x

x=76.92936

Rounding to the nearest tenth

x = 76.9

The ratio of the area of ∆ABC to the area of ∆DEF is; 1:100.

<h3>What is the ratio of the area of ∆ABC to the area of ∆DEF?</h3>

Since, a major criterion for similarity and congruence of triangles is that the ratio of corresponding sides are equal.

On this note, since the task content suggest that the ratio of the perimeters is; 1:10, it follows from conventional mathematics that the ratio of their areas is given as; 1²:10²; 1:100.
