Answer:

x=13

Step-by-step explanation:

the angles shown are vertical angles so they are going to have the same value so to find x we setup an equation and the equation would be

-3x+14=-x-12 and the we solve for x

step 1 add 3x to each side

14=2x-12

step 2 add 12 to each side

26=2x

step 3 divide each side by 2

x=13

Answer:

$\Huge\boxed{25.13ft^3}$

Step-by-step explanation:

Hello There!

It says the tree has a cone like structure

The formula for volume of a cone is

$V=\pi r^2\frac{h}{3}$

where r = radius and h = height

note it says to use 3.14 for pi

so given the dimensions all we have to do is plug in the values into the formula

$V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133$

Our last step is to round to the nearest foot

So we can conclude that the tree has a volume of 25.13ft³

Answer:

see explanation

Step-by-step explanation:

Using the cosine and tangent trigonometric ratios and the exact values

cos30° = $\frac{\sqrt{3} }{2}$ and tan30° = $\frac{1}{\sqrt{3} }$ , then

cos30° = $\frac{adjacent}{hypotenuse}$ = $\frac{6}{m}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

$\sqrt{3}$ × m = 12 ( divide both sides by $\sqrt{3}$ )

m = $\frac{12}{\sqrt{3} }$ ← rationalise by multiplying numerator/ denominator by $\sqrt{3}$ )

m = $\frac{12}{\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$ = $\frac{12\sqrt{3} }{3}$ = 4 $\sqrt{3}$

-------------------------------------------------------------------------------

tan30° = $\frac{opposite}{adjacent}$ = $\frac{n}{6}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

$\sqrt{3}$ × n = 6 ( divide both sides by $\sqrt{3}$ )

n = $\frac{6}{\sqrt{3} }$ ← rationalise the denominator

n = $\frac{6}{\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$ = $\frac{6\sqrt{3} }{3}$ = 2 $\sqrt{3}$
