∠yxz and ∠zxw are adjacent and supplementary angles. if m∠yxz = 37°, what is m∠zxw? a. 143° b. 37° c. 53° d. unknown

Choice A) 143 degrees

To get this answer quickly, you subtract the given angle (37) from 180 to get 180-37 = 143

The more longer answer would look something like this
x+37 = 180 the two supplementary angles add to 180 degrees
x+37-37 = 180-37 subtract 37 from both sides
x+0 = 143
x = 143
where x is the measure of angle ZXW
