Question

Two complamentry angles differ by 120degrees ,find the angles

Answer 1

if one angle say 'x'another angle say 'x+12'the sum of two angles =90

x+x+12=90

2x+12=90

2x=90-12

2x=78

x=78/2

x=39

x+12=39+12

=51

Answer 2

Answer:

if it is 12 degrees that you have mentioned in the question the the following will be the solution

A=39, B=51

Step-by-step explanation:

complementary angles are those whose sum is equal to 90

i.e. A+B=90--->equation 1

give that 12 is a difference between two angles

A=B+12 --->equation 2

put equation 2 in equation 1

==> A+A+12=90

==>2 A=90-12

==>2 A=78

==>A=39

==>B=A+12=39+12=51
