Question

THE DIFFERENCE IN THE MEASURES OF TWO complementary angles is 12 degree. FIND THE MEASURE OF THE ANGLES.

Answer 1

let the two angles be x and x+12 degrees
according to question
x+x+12=90
2x+12=90
2x =90-12=78 degree
x=78/2=39 degree
x+12=39+12=51 degree

Answer 2

X+X+12=90
2x=90-12
X=78/2
X=39
other angle 39+12=51
