PLZ HELP ASAP RIGHT TRIANGLES

Mathematics
1 answer:
soldi70 [24.7K]3 years ago
5 0
The correct answer is 45ft(along the ground)

Explanation:
It is making the right angled triangle as one half is 28 feet tall(vertically straight); the other half which fell over some distance is the hypotenuse. To find its length:

Hypotenuse = 81 - 28 = 53

Now that we have hypotenuse and the vertical length (perpendicular), we can find the base( along the ground) using Pythagoras theorem:

c^2 = a^2 + b^2

c = hypotenuse
a = perpendicular
b = base

53^2 = 28^2 + b^2
b = 45ft (along the ground)

Explain the method for determining the correct degree and classification of a polynomial?
Rasek [7]
For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

Classification by the number of terms:
monomial<span> (1 term)
</span>binomial<span>  (2 terms)
</span>trinomial<span>  (3 terms)
</span>polynomial (<span>four or more terms</span>).

A triangle has side lengths of n, n – 3, and 2(n − 2). If the perimeter of the triangle is at least 37 units, what is the value
Vilka [71]

Answer:

n = 11

Step-by-step explanation:

The side length of a triangle are n,n-3 and 2(n-2).

The perimeter of the triangle, P = 37 units

We need to find the value of n.

Perimeter = sum of all sides

n+n-3 +2(n-2) = 37

2n-3+2n-4 = 37

4n -7 = 37

4n = 37+7

4n = 44

n = 11

So, the value of n is 11.
