m∠6+39°=90°

measure of angle 6 plus 39 degrees equals 90 degrees

m∠6+39°=180°

measure of angle 6 plus 39 degrees equals 180 degrees

m∠6=39°

measure of angle 6 equals 39 degrees

m∠6=180°−39°

measure of angle 6 equals 180 degrees minus 39 degrees

Answer 1

m∠6 + 39° = 90°

(Since complementary angles sum to 90°, so m∠6 = 90° − 39° = 51°.)
