Question

Find the m < 4.
m<4 = Answer

Answer 1

The measure of angle 4 is 44 degrees. Option D

To determine the measure of the angle, we have to know the following;

• The sum of angles on a straight line is 180 degrees
• Supplementary angles sum up to 180 degrees
• Angles at right angle is 90 degrees
• Alternating angles are equal
• Corresponding angles are equal

Then, we have that;

m<3 + 93 = 180

m<3 = 87 degrees

Then, sum of angles in a triangle

49 + m<4 + 87 = 180

collect like terms

m<4 = 44 degrees
