The value of x is 60, as you wrote. The sum of all angles in a triangle is 180°.

The sum of all angles on a straight line is also 180°. So to find y, solve for the third angle of the triangle on the left.

50 + 60 = 110. 180-110 = 70°.

Now we know 2 of the 3 angles along the line (70° and x, 60°)

70 + 60 + y = 180
130 + y = 180
y = 50

Hope this helps. LMK if you have questions.

A sawdust pile has a base diameter of 35 feet when it’s height is 30 feet, find the volume of the pile when it is at 50 feet tal

Answer:

The volume of the sawdust pile is 16041.7 feet.

Step-by-step explanation:

The sawdust pile formed is in the form of a cone.

The volume of a cone is:

$V=\frac{1}{3}\ \pi r^{2}\ h$

The information provided is:

<em>r</em> = radius of the base = diameter ÷ 2 = (35 ÷ 2) feet

<em>h</em> = height = 50 feet

Compute the volume of the sawdust pile as follows:

$V=\frac{1}{3}\ \pi r^{2}\ h$

$=\frac{1}{3}\times \frac{22}{7}\times (\frac{35}{2})^{2}\times 50\\\\=16041.6667\\\\\approx 16041.7\ \text{feet}$

Thus, the volume of the sawdust pile is 16041.7 feet.
