What is the length of the hypotenuse
nika2105 [10]

<u>Given</u>:

Given that the length of the two legs of the right triangle are 28 m and 45 m.

We need to determine the length of the hypotenuse.

<u>Length of the hypotenuse:</u>

The length of the hypotenuse can be determined using the Pythagorean theorem.

Thus, we have;

hyp^2=28^2+45^2

Simplifying, we get;

hyp^2=784+2025

hyp^2=2809

Taking square root on both sides, we get;

hyp=\sqrt{2809}

hyp=53 \ m

Thus, the length of the hypotenuse is 53 m

Hence, Option C is the correct answer.

Find the value of x in the equation 3(2x-4)-5(x-2)=1
Lyrx [107]

Answer:

x=3

Step-by-step explanation:

3(2x−4)−5(x−2)=1

Step 1: Simplify both sides of the equation.

3(2x−4)−5(x−2)=1

(3)(2x)+(3)(−4)+(−5)(x)+(−5)(−2)=1(Distribute)

6x+−12+−5x+10=1

(6x+−5x)+(−12+10)=1(Combine Like Terms)

x+−2=1

x−2=1

Step 2: Add 2 to both sides.

x−2+2=1+2

x=3

Derek is playing a prank on Grace and hid her pencil inside a tissue box that has a width of 4 inches, a length of 8 inches, and
ohaa [14]

Answer:

9.8 Inch

Step-by-step explanation:

The distance from the upper left corner to the bottom right corner of the box is the longest diagonal of the box.

For a rectangular prism:

Length of the Longest diagonal =\sqrt{ l^2+h^2+w^2}

Therefore:

Length of the pencil=\sqrt{ 8^2+4^2+4^2}

=\sqrt{96}\\=9.8$ inch(correct to  the nearest tenth of an inch)
