The relationship between supplementary angles is that they add up to 180°. So, if the measure of ∠b is 121°, then the measure of ∠a would be 180° - 121° = 59°.
Therefore, m∠a is 59°.
Angles a and b are supplementary angles. What is the value of m∠a if m∠b=43° ?(1 point) Responses 47° 47 degrees 223° 223 degrees 43° 43 degrees 137° 137 degrees
Since angles a and b are supplementary, their measures add up to 180 degrees. If m∠b is 43 degrees, then m∠a would be 180 degrees minus 43 degrees, which is equal to 137 degrees.
Therefore, the value of m∠a is 137°.
Use the relationship between supplementary angles to determine the value of y° if x°=125° . (1 point) Responses 125° 125 degrees 55° 55 degrees 35° 35 degrees 305°
The relationship between supplementary angles is that they add up to 180°. If x° is 125°, then the measure of its supplementary angle y° would be 180° - 125° = 55°.
Therefore, the value of y° is 55°.
