Answer:
What is the first part of the question? Can you put it in the comments?
Step-by-step explanation:
You a line the decimal points right above each other and add the .45 to .8
(Credit to guy/girl above) 63 miles 10 1/2 x 6 is 63.
The total 'parts' of the ratio is 10 (3+7).
Complementary angles add to 90 degrees.
Divide 90 by 10 and you get 9.
Each 'part' is 9.
3:7 * 9 = 27:63
One angle is 27 degrees and the other is 63 degrees.
