Angle map and angle mac are linear pairs ,m of angle map=7x-13 and m of angle Mac =3x+13 how do u determine m of angle map
FromTheMoon [43]

Answer : ∠map = 7\times17-13=119-13=106\textdegree

∠mac = 3\times17+13=51+13=64\textdegree

Explanation:

Since we have given that

∠map and ∠mac are linear pairs

So their sum wiil be supplementary

i.e. ∠map+∠mac= 180\textdegree;

7x-3+3x+13=180\textdegree\\10x+10=180\textdegree\\10x=180\textdegree-10\textdegree\\10x=170\textdegree\\x=\frac{170}{10}\\x=17\textdegree

So, ∠map = 7\times17-13=119-13=106\textdegree

and ∠mac = 3\times17+13=51+13=64\textdegree
