Explain how units of length and capacity are similar in the metric system. !

 In the metric system, each of the common kinds of measure -- length, weight, capacity -- has one basic unit of measure.  To measure smaller amounts, divide the basic unit into parts of ten, a hundred, or a thousand, and so on.  To measure larger amounts, multiply the basic unit by ten, a hundred, or a thousand, and so on.  

 Length:

1 kilometer (km) = 1000 meters (m)
1 centimeter (cm) = .01 meter (m)
1 millimeter (mm) = .001 meter (m)

Weight:

1 kilogram (kg) = 1000 grams (g)
1 milligram (mg) = .001 gram (g)

Capacity:

1 milliliter = .001 liter (l)

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
