IF M<1=5x+7 and M<2=7x+17, then x= ?
ps. < = the angle sign
THANKS!

set out to equal 180

We need more information. How are the two angles related? Do the two angles have the same measure? (Are they congruent angles?) Do the two angles make a straight line (supplementary), or a 90 degree angle (complementary)?
We can't solve this unless we have more info.
***************
M<1 + M<2 = 180
(5x + 7) + (7x + 17) = 180
(5x + 7x) + (7 + 17) = 180
12x + 24 = 180
12x + 24 - 24 = 180 - 24
12x = 156
12x / 12 = 156 / 12
x = 13

We need to know the sum of the two angles, or a third angle of the triangle, or at least some more information to solve this. Is there a diagram?

are these angles supplementary or complementary?
if they are supplementary add together and set equal to 180
if they are complementary add together and set equal to 90
