For this you would use Pythagorean theorem (a^2+b^2=c^2) a=15 and c=sqrt 514 plug the numbers in and you’ll be set

Hi! I don't know if I'm too late or not, but as I just answered the question on my own, I can confirm to you that the answer is:
B) 17
At first, I thought that the length of x and 15 were equal so that's what I had chosen. It was incorrect, so taking advantage of the retry, I looked at the shape slightly closer, and noticed that angle x was slightly longer.
Long story short the answer is B) 17.

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4 if the perimeter of the triangle is 13.5 inches find the

marissa [1.9K]

Answer:

The shortest side of the triangle is 3 inches.

Step-by-step explanation:

Given:

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4.

The perimeter = 13.5 inches.

Now, to find the shortest side.

<em>Let the one side be $\frac{1}{6}x$ </em>

<em>And the second side be $\frac{1}{3}x$ .</em>

<em>And the third side be $\frac{1}{4}x$ .</em>

According to question:

$\frac{1}{6}x+\frac{1}{3}x+\frac{1}{4}x=13.5$

⇒ $\frac{x}{6}+\frac{x}{3}+\frac{x}{4}=13.5$

Adding all the variables by taking common denominator we get:

⇒ $\frac{9x}{12}=13.5$

<em>Multiplying both sides by 12 we get</em>:

⇒ $9x=162$

<em>Dividing both sides by 9 we get</em>:

⇒ $x=18$

Thus, <em>the sides of the triangle are</em>:

<u>1/6×18=3 inches.</u>

<u>1/3×18=6 inches.</u>

<u>1/4×18=9/2=4.5 inches</u>.

Therefore, the shortest side of the triangle is 3 inches.

Which of the following is the solution set to the equation: 2x(x-3)(4x+1)=0?

Troyanec [42]

Answer:

(1) {-1/4, 0, 3}

Step-by-step explanation:

Step 1: Factor left side of equation.

2x(4x+1)(x−3)=0

Step 2: Set factors equal to 0.

2x=0 or 4x+1=0 or x−3=0

x=0 or x= −1/4 or x=3

tangare [24]

20 laps at 400 yds per lap = (20 x 400) = 8000 yds

1680/8000 = 0.21....multiply by 100 to get ur percent (100 x 0.21) = 21%
