Hello!
First you have to find what the temperature was at the 3 stages
It started at 87
Then went down 10
87 - 10 = 77
Then up 17
77 + 17 = 94
Then you take the difference from the current temperature from the lowest temperature
94 - 77 = 17
The answer is D
Hope this helps!

2+3x = 62
3x = 60
x = 20
52.
6x+2 + 40 = 90
6x = 48
x = 8
53.
3x+18 + 93 = 180
3x = 69
x = 23
54.
x-24 + 29 + 296 = 360
x = 59
Answer:
The Red Submersible
Step-by-step explanation:
Since it is a square, it will be 18 stones wide and 18 stones long, to get you an area of 324.
An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)
You wouldn't *really* need a protractor to complete your homework; you could guesstimate.
I hope this helps!
