Yo, well its been a while and again Im having a trouble on a math problem this time its about vertices..
here's the question, Im stuck in this for about 5 hrs now.
Two vertices of an equilateral triangle are (10,-4) and (0,6) Find the third vertex
I know their distance is 10 sqr of 2 but thats the farthest i could get.
hopefully you can help me again and as always thanks.

Yo.
I dont know if you remember me, but Im the one you help with the trigo problem. I hope you dont mind but I have another problem well its not really a problem about how to solve it, I just cant understand the question.
well here it is.
A ladder 20 feet long is set with one end at a horizontal distance of 7 feet from sloping wall. The other end of the ladder reaches 15 feet up the face of the wall. What angle does the wall make with the horizontal?
my problem is the last sentence, what angle am I looking for exactly? I use the Angle opposite of the 20 ft and I got 126°52'12'' is that correct or is it the angle opposite of the 15 ft?
Thanks~

I'm sorry, I didn't read the question closely enough and assumed it was a problem which I used to get a lot in class.
The angle that the wall makes with the horizontal means the angle created when both of them meet, where they touch each other. So in the case of my picture, it would be the angle which I thought was supposed to be 90 degrees, the one opposite angle to 20 feet. Your original answer of 126 degrees is correct.
