Answer:
56766.97
Step-by-step explanation:
We have the formula (sin x)^2 + (cos x)^2 = 1;
Then, sin α =
cos β =
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;

Given :
- The length of a rectangle is 4m more than the width.
- The area of the rectangle is 45m²
⠀
To Find :
- The length and width of the rectangle.
⠀
Solution :
We know that,
So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :
⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
