The Angle ABM is 44 degrees and Angle MBC is 76 degrees.

To find the measure of each angle in terms of x, we need to use the fact that the sum of the angles in a triangle is always 180 degrees.

Let's set up an equation:

Angle ABC + Angle ABM + Angle MBC = 180

90 + 2x + 20 + 3x + 40 = 180

5x + 150 = 180

Now, we can solve for x:

5x = 60

x = 12

Now we can substitute the value of x back into the expressions for the angles to find their measures:

Angle ABM = 2*12 + 20 = 2(12) + 20 = 44 degrees

Angle MBC = 3*12 + 40 = 3(12) + 40 = 76 degrees

The probable question may be:

Use an algebraic equation to find the measure of each angle that is represented in terms of x.

In triangle ABC , BM is angle bisector, Angle ABC= 90 degree, Angle ABM=2x+20 degree, angle MBC=3x+40 degree

measure of angle 2x+20 degree=_____degree

measure of angle 3x+40 degree=_____degree
