Triangle LMN has vertexes at L(1, 6), M(1, 6), and N(1, 1). Find the measure of angle L to the nearest degree.
(Hint: Sketch the triangle on the coordinate plane and find the side lengths using the Distance Formula first.)

Best ResponseYou've already chosen the best response.0I found the other length for LN and it would be 7.28

Best ResponseYou've already chosen the best response.0ok yes, I'd say, get the segment's length first, then use the law of cosines \(\bf \cfrac{{\color{blue}{ a}}^2+{\color{red}{ b}}^2c^2}{2{\color{blue}{ a}}{\color{red}{ b}}}=cos(C)\implies cos^{1}\left(\cfrac{{\color{blue}{ a}}^2+{\color{red}{ b}}^2c^2}{2{\color{blue}{ a}}{\color{red}{ b}}}\right)=\measuredangle C\)

Best ResponseYou've already chosen the best response.0I think you miscalculated the LM side length, it is for sure larger than 2

Best ResponseYou've already chosen the best response.0How would it not be 2. Like i did the distance formula and used the graph and its 2 lol

Best ResponseYou've already chosen the best response.0it was actually pretty easy, no law of cosines to calculate...just my plotting points wrong to start

Best ResponseYou've already chosen the best response.0have you used the arctangent function? tan^(1) ...usually 2nd or shift and tangent on the calculator
