help please!!!1.....Find the measure of angle C.... i have no clue how to do it???
The angles in all triangles add up to 180
the angles of any triangle on a euclidean plane add up to 180
lol ... you said all triangles ;)
Solve for x and then work out the size of angle C
combine like terms and it becomes a no brainer to solve for x
(8+5+7)x + (3+15+2) = 180
thats what i get confused on
Sorry, not all triangles but definitely the one your looking at :)
ohh wait let me try it
to combine like terms is simply adding apples and oranges; or in this case, xs and constants
i got 8 does that seem right?
x=8 sounds good to me, now that you know what x equals, stick it in the angles equation
5x+15 = C 8 ------- 40+15 = C
yep then i pluged 8 in and the answer is 55 degrees
that right. they try to trick you into stopping at x=8 :)
