Answer:
<u>The correct answer is D. obtuse scalene</u>
Step-by-step explanation:
1. Let's recall that a equilateral triangle has its three sides of the same length. An equilateral triangle is always equiangular. This is not our given triangle.
2. Let's recall that an isosceles triangle has two sides of the same length. This is not our given triangle.
<u>3. Finally, let's recall that in a scalene triangle, none of the sides are the same length. And if one of the given angles is greater than a right angle, measures more than 90 degrees, it is an obtuse triangle. This is our given triangle.</u>
<u>The correct answer is D. obtuse scalene.</u>
Answer:
10
Step-by-step explanation:
3 x 5 = 15 so 2 x 5 = 10
Answer:
6
Step-by-step explanation:
first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.
