Answer: 11. Is A
Step-by-step explanation:
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
What does the triangle look like? If the base angles or two of the side lines are congruent then it is a isosceles triangle. If all the angles are congruent or all the sides, then it is an equilateral triangle. If non of the angles or sides are congruent then it is a scalene triangle
