if the complement of a certain angle is 7 times the measure of that certain angle , then what is the measure of that certain angle ?  Choose the correct choice from the following answers:
A) 45 °
B) 30 °
C) 22.5 °
D) 18 °
E) 11.25 °

Rationale: thecomplementof angle a is the angle which , when added to angle a , gives 90 degrees . the two acute angles of a right triangle are complements , for example . the original angle is x , so the complement is 7 x , and together , these add up to 90 degrees . x + 7 x = 90 8 x = 90 x = 11.25 ° answer = ( e )
Answer: E
