Answer:
45
Step-by-step explanation:
All angles in a triangle add up to 180.
80 + 55 = 135
180 - 135 = 45
To find the average, add up all the numbers, then divide that answer by the quantity of numbers.
STEP 1:
add all numbers
=30 + 20 + 0 + 0 + 0 + 0 + 120
=170 total
STEP 2:
divide total from step 1 by 7 (total quantity of numbers given, including zeros)
=170 ÷ 7
=24.2857
=24.3 rounded to nearest tenth
***You could also calculate the average by adding only non-zero results (20,30,120) and then dividing by 3 (the quantity of only non-zero numbers).
ANSWER: The average number of minutes studied per day is 24.3.
Hope this helps! :)
