	Needing the area of an irregular Pentagon		2017-12-06
		Dale pose la question : I'm needing to find the square footage of an irregular pentagon. I've seen the other questions similar to this one, but without a great deal of difficulty can't get you the angle degrees, or the length between opposing angles. I'm hoping that a different bit of information can help. So here goes: The longest side is 67ft long. One of its legs is 39ft long, and the other is 18ft long. The leg off of the other end of the 39ft leg is 35ft long. The leg off of the other end of the 18ft is 49ft long, and meets the other end of the 35ft side. The information that I DO have, which I'm hoping makes the difference, is that the 39ft and the 18ft sides are parallel. Also, while the angles at each end of the 67ft side are not right angles, they are fairly close to it, approximately 80 degrees at the 39 ft side corner, and 100 degrees at the 18ft side corner.

		Gracie pose la question : i really need help with this problem in my math book, will you help? "Derrick drew regular pentagon with side lengths of 8 centimeters. He divided the pentagon into 5 identical triangles, and measured the height of one of the triangles to be 5.5 centimeters. Find the area of the pentagon." this really makes no sense to me. Can you help me with anything to make it easier? THANKS!!!!! Penny Nom lui répond.
