Best ResponseYou've already chosen the best response.0m<C = m<F m<A=m<D m<B=m<E dw:1438003089618:dw equal lines shows that m<C = m<F m<A=m<D m<B=m<E

Best ResponseYou've already chosen the best response.0first you need to find y so they gave m<D ,m<E ,m<F all triangles add up to 180 so set it equal to 180 \[\huge\rm 12y10+51+30y+13 =180\] solve for y

Best ResponseYou've already chosen the best response.0or you can set first triangle equal to 180 doesn't matter you will get the same answer m<A+m<B+m<C =180

Best ResponseYou've already chosen the best response.0This is yet another dumb question. but is the 10 a negative and how do I add hat to 1 and 13?

Best ResponseYou've already chosen the best response.0I meant 51, not 1 haha

Best ResponseYou've already chosen the best response.0well by adding i mean m<F+m<E+m<D add them together

Best ResponseYou've already chosen the best response.0and ofc m<D is 12y negative then you have to subtract

Best ResponseYou've already chosen the best response.0m<F = 30y +13 m<d= 12y 10 m<E = 51 so I just replaced m<F,m<D,m<F by their values now solve for y

Best ResponseYou've already chosen the best response.0combine like terms 't left side first you need to find y \[\huge\rm \color{reD}{12y}\color{blue}{10}\color{blue}{+51}+\color{reD}{30y}+\color{blue}{13 }=180\]

Best ResponseYou've already chosen the best response.0you can think of the 12y 10 as 12y + (10) you can rearrange the additions to look like this 12y + 30y + (10) +51+13 = 180 add up: 12 y's plus 30 more y's is how many y's? and the numbers: 51+13 + 10= ? you should get 42y +54= 180 now add 54 to both sides (write 54 on both sides) and then simplify
