Fofino [41]

Answer:

$x=0.04m$

Step-by-step explanation:

From the question we are told that:

Diameter $d=24cm$

Radius $r=24/2=>12cm$

Igniter distance $d_g=9cm$

Generally the equation for depth is mathematically given by

$r^2=4d_gx$

Therefore

$x=\frac{r^2}{4d_g}$

$x=\frac{12^2}{4*9}$

$x=4cm$

$x=0.04m$

koban [17]

Value of x is 9 and measure of each side is 35 units.

<u>SOLUTION: </u>

Given, Triangle QRS is an equilateral triangle.

QR is seventeen more than twice x, $\rightarrow QR = 17 + 2x$

RS is 19 less than six times x, $\rightarrow RS = 6x-19$

And QS is one less four times x, $\rightarrow QS = 4x-1$

We have to find x and measure of each side.

Now, we know that, sides of equilateral triangle are equal,

Then $QR = QS \rightarrow 17 + 2x = 4x-1 \rightarrow 4x-2x = 17 + 1 \rightarrow 2x = 18 \rightarrow x = 9$

So, value of x is 9.

$\begin{array}{l}{\text { Now, } \mathrm{QR}=17+2(9)=17+18=35} \\\\ {\mathrm{RS}=6(9)-19=54-19=35} \\\\ {\mathrm{QS}=4(9)-1=36-1=35}\end{array}$

Hence, value of x is 9 and measure of each side is 35.
