Answer: 23°, 65° and 92°
Step-by-step explanation:
a + b + c = 180 (The angles of a triangle equals to 180)
a = 4c (the largest angle is 4 times the smallest angle)
b = 4c - 27 (the final angle is 27 less than the largest angle)
c = c
Now that we have gotten the values for the variables in our equation, we plug them in:
4c + 4c - 27 + c = 180
Combine like terms:
4c + 4c + c - 27 = 180
9c - 27 = 180
9c = 180 + 27
9c = 207
Divide both side by 9
c = 23
a= 4c
a = 4 × 23
a = 92
b = 4c - 27
b = 92 - 27
b = 65
b = 65
Check:
a + b + c = 180
92 + 65 + 23 = 180
180 = 180
You have to multiply the 20 min by the number of student in the class which are 25. Then take the minutes and devide them by the number of minutes in an hour.
20 x 25 = 500 minutes
500/60 = 8.3333 (round down) 8 hrs
3/7 is greater.
3/7 can be written as 15/35.
2/5 can be written as 14/35.
15/35 > 14/35 thus 3/7 > 2/5.
