• m3=43°
• m4=146°

hope it helps.

Answer 2

m∠1 is 137

m∠3 is 137

m∠4 is 43

Explanation:

m∠2 and m∠4 are the same size as each other, so m∠4 is 43. m∠2 and m∠4 added together would be 86 degrees. In total, the figure will measure 360 degrees. So to find out the other measurements, subtract 86 from 360. You're left with 274, which is m∠1 and m∠3 from your figure added together. Since they are the same size as well, divide 274 by 2 and you'll get the number of degrees for m∠3 and m∠1. 274/2 is 137
