Answer:
It's actually right and scalene
Step-by-step explanation:
Since there is a ninety degree angle, it isn't obtuse or acute because the angle is a right angle. And since all the side lengths are different, it must be scalene in comparison to isoceles or equilateral.
The correct answer is 10/7 or 1 3/7. Hope this helps.
Answer:
A u B = {3,5,6,7,8,11,12}
Step-by-step explanation:
A = {3,6,7,11}
B = {3,5,7,8,12}
A u B = {3,5,6,7,8,11,12}
Add all of the interior angles to 1260. Then you simplify for x. After that you plug in what you found for X in the E expression.
The commutative property of addition means that when you see a problem, you change the order. The co in commutative means change order. That's what my teacher told me.
