There are two complementary angles, ∠5

Question

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°=180°
x plus 39 degrees equals 180 degrees

m∠6=39°
x equals 39 degrees

m∠6=180°−39°

Answer 1

The correct equation to write for the complementary angle ∠6 when m∠5 = 39° is:

m∠6 + 39° = 90°

This is because complementary angles sum up to 90 degrees.
