In OO, mbac=290°.find m<b

To find the measure of angle B, we need to know some additional information about the figure that angle B is part of. Without this information, we cannot determine the measure of angle B based on the given information that angle MBA is 290 degrees.

However, if we assume that the figure is a triangle, we can proceed as follows. In a triangle, the sum of the measures of the angles is always 180 degrees.

Let's say angle B measures x degrees.

To find the measure of angle B, we can use the given information that angle MBA is 290 degrees and the fact that the sum of angles in a triangle is 180 degrees.

We can set up the following equation:

x + 290 + C = 180

Here, C represents the measure of the third angle in the triangle.

Simplifying the equation gives:

x + C = -110

Without any additional information about the measure of angle C, we cannot determine the specific measure of angle B using the given information that angle MBA is 290 degrees.
