33.3% is the answer, I think
20/60 ---> 1/3, covert this to a percentage and it equals 33.3%
Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
7(8)+7(d)
56+7d=
The question mark would be 7.
