Height of the triangle: y
y=18 tan theta

a. theta=45°→y=18 tan 45°=18 (1)→y=18
The height of the triangle is 18 feet when theta=45°

b. theta=55°→y=18 tan 55°=18 (1.428148007)→y=25.70666412
The height of the triangle is 25.70666412 feet when theta=55°

c. Area of the triangle: A
A=(1/2)bh
Base of the triangle: b=36 feet
Height of the triangle: h=y

Theta=45°→y=18 feet→A=(1/2)(36 feet)(18 feet)
A=(1/2)(648 feet^2)→A=324 feet^2

Theta=55°→y=25.70666412 feet→A=(1/2)(36 feet)(25.70666412 feet)
A=(1/2)(925.4399083 feet^2)→A=462.7199541 feet^2

With the angle of 55° the area of the garden is greater

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

Parallel lines r and s are cut by two transversales, parallel lines t and u. which angles are corres

Answer from: Quest

the results from a pre-test for students for the year 2000 and the year 2010 are illustrated in the box plot. what do these results tell us about how students performed on the 29 question pre-test for the two years?

if we compare only the lowest and highest scores between the two years, we might conclude that the students in 2010 did better than the students in 2010. this conclusion seems to follow since the lowest score of 8 in 2010 is greater in value than the lowest score of 6 in 2000. also, the highest score of 28 in 2010 is greater in value than the highest score of 27 in 2000.

but the box portion of the illustration gives us more detailed information. the middle bar in each box shows us that the median score of 20 in 2000 is greater in value than the median score of 17 in 2010. further, we note that the box and whiskers divide the illustration into four pieces. each of these four pieces represents the same portion of students. so, the upper half of the students in 2000 scored in the same score range as the upper one-fourth of the students in 2010, see the illustration at a score of 20.

by considering the upper one-fourth, upper half, and upper three-fourths instead of just the lowest and highest scores, we would conclude that the students as a whole did much better in 2000 than in 2010. we would conclude that as a whole the students in 2010 are less prepared than the students in 2000.

in this section, we discuss box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. the key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
