there are angles whose meausre add to 180 their meaure are m a = 67 m b = 2x=20 and m c= x what is the meausre of b
To find the measure of angle b, we can use the fact that the sum of the measures of angles in a triangle is 180 degrees.
Given:
m(a) = 67 degrees
m(b) = 20 degrees
m(c) = x degrees
We know that a + b + c = 180 degrees
Substitute the given values:
67 + 20 + x = 180
87 + x = 180
x = 180 - 87
x = 93
Now that we have found the value of x, we can calculate the measure of angle b:
m(b) = 20 degrees
So, the measure of angle b is 20 degrees.
