Find the measure of angle 1.
8x - 4
16x + 8

Answer:
53°
Step-by-step explanation:
As we can see that ∠3 and ∠7 are corresponding angles. Therefore,
Now calculate the angles of ∠3 and ∠7.
Now we can see that ∠3 and ∠1 are alternate angles and ∠7 and ∠1 are alternate exterior angles. Thus, we can say that
Hence the measure of ∠1 is 53°.
