Answer:

29

Step-by-step explanation:

The length of the median of a trapezoid equals one-half the sum of the lengths of the bases.

Answer:

  50 ft

Step-by-step explanation:

The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.

In this geometry, that means the length of the escalator is 2 times its height, so is ...

How do you do number 11?
Stells [14]
\frac{a - c}{x - a} = m   Multiply both sides by (x - a)
a - c = m (x - a)   Use the Distributive Property
a - c = mx - ma  Add ma to both sides
a - c + ma = mx   Divide both sides by m
\frac{a - c + ma}{m} = x   Switch the sides to make it easier to read
x = <span>\frac{a - c + ma}{m}</span>
