Answer:
x = 11
Step-by-step explanation:
The relationship between the sine and cosine functions can be written as ...
sin(x) = cos(90 -x)
sin(A) = cos(90 -A) = cos(B) . . . . substituting the given values
Equating arguments of the cosine function, we have ...
90 -(3x+4) = 8x -35
86 -3x = 8x -35
86 +35 = 8x +3x . . . . . add 3x+35 to both sides
121 = 11x . . . . . . . . . . . . collect terms
121/11 = x = 11 . . . . . . . . divide by 11

There are other applicable relationships between sine and cosine as well. The result is that there are many solutions to this equation. One set is ...
11 +(32 8/11)k . . . for any integer k
Another set is ...
61.8 +72k . . . . . for any integer k
Answer:
81 mm
Step-by-step explanation:
Now: 1 mm
In 10 minutes: 3 * 1 mm = 3 mm
In 20 minutes: 3 * 3 mm = 9 mm
In 30 minutes: 3 * 9 mm = 27 mm
In 40 minutes: 3 * 27 mm = 81 mm
Answer: 81 mm

Answer:
Follow the steps and it will help on all the problems and it should help you out.
Step-by-step explanation:
- You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
- You only multiply or divide, never add or subtract, to get an equivalent fraction.
- Only divide when the top and bottom stay as whole numbers.
