If mThe image shows an angle symbol.3 = 42°, what is mThe image shows an angle symbol. 2?

Three arrows are shown. The first and second are parallel and travel left to right. The third is transverse, traveling through the parallels. The 4 top angles are labeled 1, 2, 4 and 3; the bottom 4 angles are labeled 5, 6, 8 and 7 (clockwise order).
A. 42°
B. 48°
C. 90°
D. 138°

Without further information, we cannot determine the measure of angle 2.

To find the measure of angle 2, we need to understand the relationship between the angles formed by a transversal intersecting two parallel lines.

Based on the given information, we know that angle 3 is 42°. When a transversal intersects two parallel lines, the corresponding angles are congruent. This means that angle 2 is also 42°.

Therefore, the measure of angle 2 is 42°.
