There are two complementary angles, ∠5 and ∠6 . If m∠5=39° , what equation can you write to solve for m∠6 ?(1 point)
Responses
m∠6+39°=90°
x plus 39 degrees equals 90 degrees
m∠6=39°
x equals 39 degrees
m∠6+39°=180°
x plus 39 degrees equals 180 degrees
m∠6=180°−39°
m∠6=180°−39°
Two angles, ∠1
and ∠2
