Using satellite technology, the distance between two planes can be measured by keeping track of the angle between them and the d

istance of each plane to the tracking station. Assume plane 1 is 176.27 miles away d plane 2 is 222.34 miles away and the angle formed with the tracking station is 38.59. How far apart are the planes?

The best approach to this is to use the law of cosine which is stated as  
c2 = a2 + b2 â’ 2ab cos(C)
 distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value. 
 Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles

Determine the area of a parallelogram if<br> its base is 16 cm and its height is 7 cm.
ella [17]
<h3>Answer: 112 square cm</h3>

=====================================

Work Shown:

area = base*height

area = 16*7

area = 112 square cm

----------------

Extra info (optional section):

The area formula for a parallelogram is the same as the formula for a rectangle. Imagine tilting a rectangle so that it's slanted. The area has not changed.

Or another thing to imagine is that let's say we had a stack of 2 by 4s. If the stack is perfectly vertical, aka forming a rectangle, then we can nudge the beams so that we can form a slanted parallelogram instead. Both configurations involve the same amount of wood, and therefore would lead to the same frontal surface area.
