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°=180°
x plus 39 degrees equals 180 degrees

m∠6+39°=90°
x plus 39 degrees equals 90 degrees

m∠6=39°
x equals 39 degrees

m∠6=180°−39°
x equals 180 degrees minus 39 degrees

Answer 1

Complementary angles are two angles whose measures add up to 90°. Since ∠5 and ∠6 are complementary angles and m∠5 = 39°, you can set up the equation:

\[
m∠6 + 39° = 90°
\]

Therefore, the correct response is:

**m∠6 + 39° = 90°**
