Please help me it’s due right now?!?! <br> Find the missing side of each triangle.
Sever21 [200]

Answer:

x = 2√5

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

You can identify that x is the hypotenuse, as it is opposite to the right angle.

So:

3² + √11² = x²

9 + [(√11) (√11)] = x²

9 + 11 = x²

20 = x²

√20 = √x²

√4√5 = x

2√5 = x

x = 2√5

If X=3, What is the area of a triangle with sides, 6x ,7x, and 21x? A.117 in² B.378 in² C.189 in² D. 58.5 in²
AURORKA [14]

Answer:

The given sides does not form a triangle

Step-by-step explanation:

The given sides does not form a triangle

We know the triangle property which states that the sum of any two sides of the triangle should be greater than the third side.

Here given th esides of the triangle are 6x,7x,21x

6x+7x=13x < 21x

for any value of x the above equation does not satisfy.

If f(x)=x-3, which inequality can be used to find the domain of f(x)?
Scrat [10]

Given that,

f(x) = \sqrt{x-3}

To find,

The domain of f(x).

Solution,

We have, f(x) = \sqrt{x-3}

To find domain,

The term under the square root must be positive or null as follows :

x-3\ge 0

Adding 3 both sides

x-3+3\ge 0+3\\\\x\ge 3

So, the domain is x-3>0 .

Please help, I really desperate
Paladinen [302]

Answer:

V candle ≈ 196.9 cm³

Step-by-step explanation:

Volume of cone = ( π·r²·h)/3

V candle = V big cone -V small cone

V candle = [ π·4²·(8+5) - π·2²·5]/3

V candle = ( π·16·13 - π·4·5)/3

V candle = (π·16·13 - π·4·5)/3

V candle = π·(208 - 20)/3

V candle = π·188/3

V candle = 196.8731396

V candle ≈ 196.9 cm³
