Since a square is a parallelogram, and all parallelograms have two parallel sides, a square has two parallel sides.
Answer: C
Working out: (55,000 x 20) - (30,000 x 20) = $500,000
$1,100,000 - $600,000 =$500,000
Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
<h3>
Answer: Approximately 119.76 meters</h3>
===================================================
Work Shown:
x = starting length of the shadow
y = height of the pole
tan(angle) = opposite/adjacent
tan(58) = y/x
1.6003345 = y/x
1.6003345x = y
x = y/1.6003345
x = (1/1.6003345)y
x = 0.62486936y
-------------------------
When the angle changes, the adjacent side gets 90 meters longer
tan(angle) = opposite/adjacent
tan(36) = y/(x+90)
0.72654253 = y/(0.62486936y+90)
0.72654253(0.62486936y+90) = y
0.453994166y + 65.3888277 = y
65.3888277 = y-0.453994166y
65.3888277 = 0.546005834y
0.546005834y = 65.3888277
y = 65.3888277/0.546005834
y = 119.758478075162
y = 119.76
The height of the pole is about 119.76 meters.
