There are angles whose measures add to 180 their measures are MA equals 67MB equals 2X +20 and MC equals X what is the measure of B
To find the measure of angle B, we can use the fact that the sum of the measures of all three angles is 180 degrees.
MA + MB + MC = 180
Substituting the given values:
67 + (2x + 20) + x = 180
Simplifying the equation:
3x + 87 = 180
Subtracting 87 from both sides:
3x = 93
Dividing both sides by 3:
x = 31
Now we can find the measure of angle B:
MB = 2x + 20
MB = 2(31) + 20
MB = 62 + 20
MB = 82
Therefore, the measure of angle B is 82 degrees.
