Perpendicular lines aretwo distinct coplaner lines that intersect to form what type of angle?

1 answer:

4 0

If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. If two sides of two adjacent angles are perpendicular, then the angles are complementary.

If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line.

Since the train travels 50 miles in 1 hour, to find 3/4 of an hour:

3/4 * 50
75/2 miles

I don't understand these problems

So given the values on the number line, AB and BC, adding them together will get the length of AC. If AB equals $x-3$ and BC equals $5$ , the value of AC should be $x-3+5$ . Since you are given the length of AC, $21$ , you can create an equation to solve for x. This equation would be $x-3+5=21$ . Isolating the x on the left (or right hand side) gets the value of x to be 19. The same thing goes for the 2nd question.
