Find m∠1 if m∠2=73°, m∠3=107°, m∠4=92°. justify your response!

92°

Step-by-step explanation:

The supplementary relationship between angles 2 and 3 means lines a and b are parallel. Since those lines are parallel, corresponding angles 1 and 4 are congruent.

m∠1 = m∠4 = 92°

92

Step-by-step explanation:

Actually, we can prove lines a and b are parallel.

<3 and the angle to its right form a linear pair. Since linear pairs are supplementary, those two angles have a sum of 180. Therefore, that missing angle = 73 degrees.

Thus, since the corresponding angles are equal, a and b are parallel.  That means m<1 = m<4  since corresponding angles formed by parallel lines have equal measure.

Thus, the m<1 = 92 degrees.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
