<h3>
Answer: 139.5</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(55) = 80/x
x*cos(55) = 80
x = 80/cos(55)
x = 139.4757 approximately
x = 139.5
3 3/4÷ 1/4
15/4÷1/4
15/4÷4/1
15*4=60
4*1=4
60/4=15
15 times 1/4 can fit into 3 3/4.
Answer:
A) 1:4
Step-by-step explanation:
#We first calculate the campus' area:

#We then calculate the campus' map area in square ft:

Ratio is a comparison between two dimensions:

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4
The answer should be 24, because you can mark out 5,and 10 cuz it doesn’t make since
