if angle a equals 91 degrees and angle b equals 40 degrees what is the measurement of angle 1 on a triangle?
assuming that angle 1 is the 3rd angle of a triangle whose other two angles are a and b, then you have
91+40+(angle 1) = 180
To find the measurement of angle 1 in a triangle, we need more information about the triangle. The sum of the angles in any triangle is always 180 degrees, so if we know the measurements of two angles, we can find the third angle.
In this case, you provided the measures of angle a (91 degrees) and angle b (40 degrees). To find angle 1, we can use the equation:
angle 1 + angle a + angle b = 180 degrees
Substituting the values you provided:
angle 1 + 91 degrees + 40 degrees = 180 degrees
Now, we can solve for angle 1:
angle 1 = 180 degrees - 91 degrees - 40 degrees
angle 1 = 49 degrees
Therefore, the measurement of angle 1 in the triangle is 49 degrees.
