Question

1. sat/act in the diagram, a || b. what is m∠1?

a 28
b 62
c 90
d 118

Explanation:

Step1: Identify angle - relationship

Since \(a\parallel b\), \(\angle1\) and the \(62^{\circ}\) angle are corresponding angles.

Step2: Apply corresponding - angles property

Corresponding angles formed by two parallel lines and a transversal are congruent. So \(m\angle1 = 62^{\circ}\).

Answer:

B. 62
