?
Step-by-step explanation:
I can't see anything attached but I know all angles of a triangle add up to 180 degrees. It probably doesn't help tho.
Answer:
5
Step-by-step explanation:
To obtain the total score for all the 20 students, we multiply the average score by the number hence
Total score for all 20 is 81*20=1620
Similarly, for the 19 students, the sum of their total score equals the product of the average and number of students hence
Total score for 19 readable is 19*85=1615
The difference between these two total scores ie for 20 and 19 students equals to the value of unreadable score. Therefore,
Difference=1620-1615=5
Therefore, the value of unreadable score is 5

Hello there!
On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this :
10x + 1 = 12x - 5
-2x = -6
x = 3
So the answer is x = 3.
In some problems, you have to find the angle.
Then you just simply substitute 3 into x.
10x + 1
10(3) + 1
30 + 1
31
12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.
Hope this helped! :)
