Rule-3 angles of a triangle =180 degrees . One angle is a right angle which is 90 degrees so the remaining 2 must equal 90 so the equation is so 90=(15x)+(8x-2) and now we just have to solve what is the value of x.
First we move -2 to the other side of the equation as +2 so we get 92=15x+8x next we put the 15x and 8x together and get 23 so 92=23 times x. So we divide 92 by 23 and the value of x is 4

Answer:

Volume of the Figure $=825.38m^3$

Step-by-step explanation:

Volume of the figure = Volume of the Upper cone+Volume of the lower cone

Volume of a cone = $\pi *r^2*\frac{h}{3}$

Volume of the Upper Cone with

$height=12m$

$radius=6m$

$3.14*6*6*\frac{12}{3}$

$=3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3$

Volume of the Lower cone with $radius=6m$ and $height=18m$

$=3.14*6*6*\frac{18}{3} \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3$

Volume of the Whole Figure = $147.14+678.24$

Volume of the Figure $=825.38m^3$
