Question

The measure of Angle DAB equals 105°. The measure of Angle ACB equals 35°. What is m Angle ABC? ​

Answer 1

Angle B / angle ABC = 70 degrees

Explanation:

well angle B plus angle C will equal the outer angle

so if angle C is 35 and you have the outer angle just subtract and get

angle B to equal 70

Answer 2

70°

Explanation:

the measure of an exterior angle is equal to the sum of two interior angles so 105° = ABC + 35

105 -35 = ABC

70° = ABC
