in a geometric diagram a and b are complementary and they form a straight line with c = if m a = x m b = 2x and m c = 90 what is the meausre of b
Since angles A and B are complementary, we know that angle A + angle B = 90 degrees. Given that angle A = x and angle B = 2x, we can set up the equation:
x + 2x = 90
Combining like terms, we get:
3x = 90
Dividing both sides by 3:
x = 30
Therefore, angle B is equal to:
2(30) = 60 degrees
So, the measure of angle B is 60 degrees.
