It would be 60 degrees because compliment means 90 degrees. In order to find m<CBD, you would need to subtract 30 degrees from 90 degrees which would equal 60 degrees. 90-30=60
D you put in 5 in place of where the n is

Answer:
- ∠W = 130
- ∠X = 140
- ∠Y = 50
- ∠Z = 40
Step-by-step explanation:
Using 'y' and 'z' to represent angles with the corresponding names, we have ...
y + z = 90
(3b -1) +(2b +6) = 90 . . . . substitute the given expressions
5b +5 = 90 . . . . . . . . . . . . simplify
b +1 = 18 . . . . . . . . . divide by 5
b = 17 . . . . . . . . subtract 1
Then the angles are ...
y = 3b -1 = 3(17) -1 = 51 -1 = 50
z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be
Angles W and Y form a linear pair, so are supplementary:
W = 180 -Y = 180 -50 = 130
Angles X and Z form a linear pair, so are supplementary:
X = 180 -Z = 180 -40 = 140
Then the angle measures are ...
- ∠W = 130
- ∠X = 140
- ∠Y = 50
- ∠Z = 40
Answer:
0.98 cents
Step-by-step explanation:
All you do to solve this is ou do 11.76 divided by 12
11.76 divided by 12 is actually just 98 cents (0.98)
