Mary says the pen for her horse is an acute right triangle. is this possible? explain.

Yes it is absolutely possible. A horse pin can be any shape or size. So if she want's her horses pen to be an acute triangle it can be. Hope this helps!

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The answer is 225 miles per 4.5 hours. hope this ; )
