So
y=-10x-29 and y=-59
substitute the y in the equation for -59:
-59=-10x-29
add 29 on both sides
-30=-10x
divide both sides by -10
3=x
so,
x=3
MBOA=360-250=110, so mBDA= half of mBOA=55
mBCA=180-mBOA=180-110=70
mBDA=55 and mBCA=70
The answer is 4 for this problem.

Answer:
The easiest way to solve this system would be to use substitution since x is already isolated in the first equation. Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method
