That's an isosceles triangle lying on its side.  The base angles (on the left) are marked equal, so we know the sides opposite them are equal.

That means that  . . . x+4 = 3x-8

Subtract 'x' from each side . . . 4 = 2x-8

Add  8  to each side . . . 12 = 2x

Divide each side by 2 . . . <em>6 = x</em>

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use th
Archy [21]

Answer:

  (a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

__

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an <em>explanation</em> of the slope, not its function in the equation. That is why we have chosen the first answer.

Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pyth
ehidna [41]

Answer:

x = 4√2

Step-by-step explanation:

<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>

To solve, we will follow the steps below:

using Pythagoras theorem

opposite² +  adjacent² = hypotenuse²

14² + y² = 18²

196 + y² = 324

subtract 196 from both-side of the equation

196 -196 + y² = 324-196

y² =128

Take the square root of both-side

√y² = √128

y =√128

y = √64×2

y =√64×√2

y = 8√2

x = half of y

x = y/2

x = 8√2  ÷  2

x = 4√2
