An angle x is 66 less than it’s complement. what is the angles measure?

12 and 78

Step-by-step explanation:

The sum of complementary angles is 90 o

X+(x-66) = 90

2x = 156    x =  78

78-66 = 12

ratio is 2 : 9

the answer is three

13.5 : 3

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
