Answer:
10 rad 3 / 2
Step-by-step explanation:
x = missing angle of the full traingle
180 - (90 + 60) = x
180 - 150 = x
30 = x
10 rad 3 / 2 = x
this is just my understanding of the problem- im sorry if im incorrect
----------------------------------------------
Define x:
----------------------------------------------
Let x be the number of students in the second class:
⇒second class = x
There are 3 more students in the first class than in the second class:
⇒first class = x + 3
There are 2 more students in the third class than in the second class:
⇒third class = x + 2
----------------------------------------------
Expression for each class:
----------------------------------------------
First class = x + 3
Second class = x
Third class = x + 2
----------------------------------------------
Expression for total number of students:
----------------------------------------------
Total = x + 3 + x + x + 2
Total = 3x + 5
----------------------------------------------
Find x:
----------------------------------------------
There are 80 students in total, so
3x + 5 = 80
3x = 75
x = 25
----------------------------------------------
Find the number of students in each class:
----------------------------------------------
First class = x + 3 = 25 + 3 = 28
Second class = x = 25
Third class = x + 2 = 25 + 2 = 27
--------------------------------------------------------------------------------------------
Answer: There are 25 students in the second class.

Answer:
three basic methods of graphing linear functions.
The first is by plotting points and then drawing a line through the points.
The second is by using the y-intercept and slope.
The third is applying transformations to the identity function f(x)=x.
