Answer:

The length of the missing side is 41.24 inches

Step-by-step explanation:

* Lets talk about the Pythagoras theorem

- It used in the right angle triangle

- The hypotenuse is the opposite side to the right angle and it's the

  longest side in the triangle

- The two other sides in the right angle triangle are the legs of

 the right angle

- If the length of the hypotenuse is c units and the lengths of the

 two legs of the right angle area a and b

∴ a² + b² = c² ⇒ c = √(a² + b²)

* Now lets solve the problem

∵ The length of the hypotenuse = 45 inches

∵ The length of one legs of the right angle = 18 inches

- Lets use the Pythagoras theorem

∴ c² = a² + b²

∴ 45² = 18² + b² ⇒ subtract 18² from both sides

∴ b² = 45² - 18² = 2025 - 324 = 1701 ⇒ take square root for both sides

∴ b = √1701 = 41.24 inches

<h2>Hello!</h2>

The answer is:

The missing side length is 41.24 inches.

<h2>Why?</h2>

Since we are working with a righ triangle, to solve this problem we can use the Pythagorean Theorem.

The Pythagorean Theorem states  that:

Hypotenuse^{2}=(Side_{1})^{2}+(Side_{2})^{2}

We are given that:

Hypotenuse=45in\\Side_{1}=18in

So, isolating the missing side and substituting the given information, we have:

(45in)^{2}=(18in)^{2}+(Side_{2})^{2}

(Side_{2})^{2}=(45in)^{2}-(18in)^{2}+

\sqrt{(Side_{2})^{2}} =\sqrt{(45in)^{2}-(18in)^{2}}\\\\Side_{2}=\sqrt{2025in^{2}-324^{2}}=\sqrt{1701^{2}}\\\\Side_{2}=41.2431in=41.24in

Have a nice day!

Drag steps of the solution into order to solve for x in the equation 6(x-5) = 54
telo118 [61]

The steps of the solution into order to solve for x in the equation 6(x-5) = 54 are:

  • A. 6x – 30 = 54
  • B. 6x = 84  
  • D. x = 14

Given the expression 6(x-5) = 54

Expand the expression in parenthesis using the distributive law;

6x - 6(5) = 54

6x - 30 = 54

Add 30 to both sides

6x - 30 + 30 = 54 + 30

6x = 84

Divide both sides by 6

6x/6 = 84/6

x = 14

Therefore the steps of the solution into order to solve for x in the equation 6(x-5) = 54 are:

  • A. 6x – 30 = 54
  • B. 6x = 84  
  • D. x = 14

What number should be added to 95 to get a sum of −21?
Natali [406]

Answer: -116

Step-by-step explanation: Since negative numbers are involved, the best way to solve this is add 95 and POSITIVE 21. This gives you 116. Since you move from a positive to a negative, the 116 needs to be negative
