use the relationship between supplementary angles <a and <b. what is m<a if m<b=121 dagees

Answer 1

If <b is an angle measuring 121 degrees, and <a is supplementary to <b, then the sum of <a and <b is 180 degrees.

So, if m<b = 121 degrees, then the measure of <a (m<a) would be:

m<a = 180 degrees - m<b
= 180 degrees - 121 degrees
= 59 degrees

Therefore, m<a would be 59 degrees.
