What seems to always be true
about the height of the triangle?

The height of the triangle is always the  measurement of a line (often shown as dashes) that is perpendicular to the base and extends to the opposite angle at the top of the triangle.

If it is a right triangle, and the right angle is at the bottom, the side extending up from the right angle will be the height. But this is not always the case.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
