Answer:

$166\frac{2}{3}\ m$

Step-by-step explanation:

Let

x ----> the average depth of the resulting layers of ash and rock

we know that

To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.

$\frac{100\ km^3}{600\ km^2}=\frac{1}{6}\ km$

Convert to meters

Remember that

$1\ km=1,000\ m$

$\frac{1}{6}\ km=\frac{1}{6}(1,000)=\frac{1,000}{6}=\frac{500}{3}\ m$

Convert to mixed number

$\frac{500}{3}\ m=\frac{498}{3}+\frac{2}{3}=166\frac{2}{3}\ m$

What is the answer?

Answer:

$x = 27$

Step-by-step explanation:

Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.

$3x - 10 + 2x + 10 + 45 = 180$

Now simply silve the equation to find x.

$5x + 45 = 180 \\ 5x = 135 \\ x = 27$

There is your answer.
