Answer 1

The measure of m<ADB is 38 degrees

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

• Alternating angles are equal
• Corresponding angles are equal
• Angles on a straight line is 180 degrees

Then, from the diagram shown, we have that;

7x - 4 = 2x + 26

collect like terms

7x - 2x = 26 + 4

add the like terms

5x = 30

Divide by the coefficient

x = 6

Then, we have;

7(6) - 4

42 - 4 = 38 degrees
