If there is no expression, it surely is equal to 0.
We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.
Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:
Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.
Simplify:
Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:
Hope this helps!
We are asked to find the proportion of sugar to number of cookies
Sugar = 200g
Number of cookies = 48
proportion of sugar to cookies = 200 : 48
how many cookies he can make with 350 grams of sugar?
let x = number of cookies
proportion of sugar to cookies = 350 : x
equate the <em>proportions</em>
200 : 48 = 350 : x
200/48 = 350/x
cross product
200 × x = 350 × 48
200x = 16800
x = 16800/200
x = 84 cookies
find the number of cookies, y, Ezra can make with x grams of sugar?
y = grams of sugar, x / number of cookies
y = 350/84
y = 4.17x
Therefore,
Ezra can make 84 cookies with 350 grams of sugar

Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Answer:
Area of a triangle is base times height divided by 2. The formula for finding the area of a parallelogram is easiest to just break it down into two triangles and 1 square/rectangle. Then just find the area of all then add them together to get the final area.
