If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
Answer:
x = 7
Step-by-step explanation:
40x ÷ 10 = 28
40x ÷ 10 × 10 = 28 × 10
40x = 280
40x ÷ 40 = 280 ÷ 40
x = 7
Part a y=95x
Part b 285=95•3
Part c ?
Hope I helped sorry I don't know how to do the last one!
Answer:
855.8
Step-by-step explanation:
hundreds tens ones . tenths hundredths thousandths
8 5 5 . 7 8 8
We are rounding to the nearest tenth, so we look at the next number which is 8. 8>= 5 so we will round the 7 up
855.788 rounds to 855.8
We can't find explicit values for 
and 
, since there is only one equation, but two variables.
The best we can do is solve for one variable with respect to the other:
Solve for :
subtract 
from both sides:
divide both sides by 
:
Solve for :
subtract 
from both sides:
divide both sides by 
:
