Answer:
Step-by-step explanation:
So first we need to make sure we know the trig identities to solve this problem.
Here we only have two legs of the triangle, so we will need to use the Pythagorean Theorem a² + b² = c² to solve for the missing leg, the hypotenuse in this case.
- Solving for the hypotenuse, c, we get
- Here a = 20 and b = 21, so plugging in these values to the equation we get:
Now we can use the trig identities to figure out the missing values for the problem
Answer:
(x-7) (x^2-5)
Step-by-step explanation:
x^3-7x^2-5x+35
Factor out an x^2 from the first two terms and -5 from the last 2 terms
x^2 (x-7) -5(x-7)
Factor out (x-7)
(x-7) (x^2-5)
Answer:
Answer is A
A contains all the elememts common to both the sets and thus it is the inteesection of the given two sets.
I hope this helps you

The area of a rectangle can be calculated by the product of its length and the width. Here we are given the area and the length so we can simply calculate for width. The perimeter is the sum of all the side lengths of the shape. We calculate as follows:
Area = lxw
1/6 = 1.5w
w = 1/9
Perimeter = 2l + 2w
Perimeter = 5/9
Hope this answers the question. Have a nice day.
