Answer:
Step-by-step explanation:
First, instead of doing 1395, let's find its coterminal angles. We can do so by subtracting 360 until we reach a solvable range. So:
This is still too high, continue to subtract:
So, instead of 1395, we can use just -45.
So, evaluate each trig function for -45:
1)
Remember that we can move the negative inside of the sine outside. So:
Remember the sine of 45 from the unit circle:
2)
Remember that we can ignore the negative inside of a cosine function. So:
Evaluate using the unit circle:
Now, remember that tangent is sine over cosine. So: "
We already know them. Substitute:
Simplify:
And we're done!

Answer:
6 yards long
Step-by-step explanation:
1/3 yards wide = 2 yards long
Let x = length of the other rug
1 yard wide = x yards long
1/3 : 2 = 1 : x
1/3 ÷ 2 = 1 ÷ x
1/3 × 1/2 = 1 / x
1/6 = 1/ x
Cross product
1*x = 6*1
x= 6 yards
Therefore, the length of the new rug with 1 yard wide is 6 yards long
The first thing to do is to find the ratio of wide to long of the two rugs by representing the long of the second rug with x
It is the simplest method to solve the question
