Question
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°
x equals 39 degrees

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

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

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

Answer 1

Since the angles ∠5 and ∠6 are complementary, their measures add up to 90 degrees. Given that m∠5 = 39°, we can write the equation:

m∠6 + 39° = 90°

So the correct response is:

m∠6 + 39° = 90°
