Answer:
(a) Because it is an exterior angle
(b) The measure of angle 2 is 72°
Step-by-step explanation:

<2=30°+42°
<2=72°
Hi!
<h3>To divide a fraction, you multiply by the reciprocal of the second fraction.
</h3><h3>First, convert the mixed numbers to fractions, by multiplying the denominator by the whole number and adding that to the numerator. </h3>
