Answer:

x = 17

Step-by-step explanation:

in such a constellation (two beams from the same point of origin cut through the same circle) the relative relation between the segments of these beams to the overall length of the beam have to be the same :

7 × (7+x) = 8 × (8+13)

49 + 7x = 8 × 21 = 168

7x = 119

x = 17

Answer:

Here's how I would do it.

Step-by-step explanation:

If two triangles are similar, corresponding sides are in the same ratio.

We know the measures of b and a, so we can calculate the ratio b/a.

d and b are in the same ratio, so

$\begin{array}{rcl}\dfrac{d}{c}& = & \dfrac{b}{a}\\d & = & c \times \dfrac{b}{a}\\\end{array}$

We know the measures of c, b, and a, so we can calculate the value of d.

Distribute and simply 7-2(x-5)+3x

KonstantinChe [14]

The given expression is

$7-2(x-5)+3x$

First, we use the distributive property to get rid of the parenthesis.

$7-2x+10+3x$

Then, we reduce like terms. -2x and 3x are like terms, also 7 and 10 are like terms.

$3x-2x+10+7=x+17$ <h2>Therefore, the simplest form of the given expression is <em>x + 17</em>.</h2>
