Question:
What is the measure of 3?
Answer:
The measure of angle 3 is 60 degrees, the correct option is B.
Given
In the diagram, g is parallel to h.
The measurement of angle 1 is (4x +36).
The measurement of angle 2 is (3x-3).
Interior angles;
The angles that lie in the area enclosed between two parallel lines that are intersected by a transversal are also called interior angles.
∠1 and ∠2 are the same side interior angles and are supplementary then the sum of both angles is equal to 180 degrees.
The measure of the angle 2 is = 3(21)- 3= 63 – 6 = 60 degrees.
Hence, Angle 2 and ∠3 are alternate angles and congruent then the measure of angle 3 is 60 degrees.
