There are two complementary angles, ∠5 and ∠6 . If m∠5=39° , what equation can you write to solve for m∠6 ?(1 point)

Question

Responses

m∠6+39°=180°
x plus 39 degrees equals 180 degrees

m∠6=39°
x equals 39 degrees

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

m∠6=180°−39°

Answer 1

Since angles ∠5 and ∠6 are complementary, their measures add up to 90°. Therefore, you can write the following equation to solve for m∠6:

m∠6 + 39° = 90°

So the correct option is:

m∠6 + 39° = 90°
