<h3>Answer: Altitude</h3>

Explanation:

An altitude goes from a vertex point to the opposite side, such that it is perpendicular to the opposite side. The square angle marker indicates we have a 90 degree angle, so DB is perpendicular to AC. The altitude of a triangle, DB, is the height of the triangle with base AC. The base and height are always perpendicular to one another.

In the figure shown, what is the measure of angle x?
mojhsa [17]
Angles in a triangle must add up to 180, so the missing angle inside the triangle is 180 - (70 + 40), which is 70.

Angles on a straight line (i.e. the line BD) must add up to 180, and because we know part of that angle is 70, x must be 180 - 70, which is 110.

Hence, x is 110 degrees.

In early spring, you are wanting to purchase 6 potted rose plants. The plants to choose from come in 8-inch pots that sell for $
topjm [15]
Things we know:
Six total pots = # of 10" + # of 8"
$78 total = cost of 10" + cost of 8"

So:
6 = x +y
and
78 = x*(cost of x) + y * (cost of y)
78 = x*12 + y*15

We need:
x+y=6  AND 12x+15y=78

So our answer can only be B.
