Angles a and b are supplementary angles what is the value of MA if MB =43
Since angles a and b are supplementary angles, the sum of their measures is 180 degrees.
Let MA=x. Since angles a and b form a straight line, we know that MA + MB = 180.
Substituting in the given value for MB, we have x + 43 = 180.
Solving for x, we subtract 43 from both sides of the equation:
x = 180 - 43 = 137.
Therefore, MA = 137.
