I don't know if my answer is completely correct, but I think it's 100. All triangles add up to 180, and an isosceles triangle has 2 equal sides. 40 would be the 2 sides, and 180 subtracted from 80 equals 100.
<h3>Answer :</h3>
<u>Given</u> :
- 9(m + 5) - 3(m - 2) = 8m + 31
We have to find value of m
➠ 9(m + 5) - 3(m - 2) = 8m + 31
➠ 9m + 45 - 3m + 6 = 8m + 31
➠ 9m - 3m + 45 + 6 = 8m + 31
➠ 6m + 51 = 8m + 31
➠ 51 - 31 = 8m - 6m
➠ 20 = 2m
➠ m = 20/2
➠<u> m = 10</u>

Answer: Alice's team
Step-by-step explanation: Add twelve and six you get 18; add 15 and 18 you get 33; now 18- 12= 6 so Alice won 6 games out of 18 so that ratio is 6:12 12-6=6; while Lucy's team's ratio is 15:18, 18- 15= 3. 3 is less than 6 so Alice's team had a higher ratio of wins to loses.
Answer: 9 cm
Step-by-step explanation:
The formula of the area of a square is
A = s²
The ‘A‘ stands for area and the ‘s’ stands for side measure.
Now, since you already know the side measure, it’s 3cm, you just have to put it into the equation.
So, now you have:
A = 3²
A = 9
Therefore, the area of the square is 9 cm.
