Answer:
The value of the third reading is 80 F
Explanation:
Let x represent the value of the third reading.
The average of a set of data equals the sum of all the data divided by the number of data;
Given;
Average = 80 F
Sum of data = 65+85+x+90
Number of data = 4
substituting we have;
solving for x;
Therefore, The value of the third reading is 80 F

tan(A)=perpedicular /base
perpendicular is just opposite of Angle(A) that is BC and base is AC
so tan(A)=BC/AC
