Answer:
118
Step-by-step explanation:
the length ED is equal to EC
so
the angle is also the same
that's mean the angle ECD is equal to 31
then to find the another angle just do like this
=180–31–31
=118
It is the last one, 1,130.4 ft^3. The volume of a cylinder equals pi (in this case 3.14) multiplied by the radius squared multiplied by the height. (3.14x6^2x10)
Answer: 15
Step-by-step explanation:
Shown in the figure below
<h2>
Explanation:</h2>
First of all, we have the following equation:

This is the equation of a line given in Slope-intercept form as the form:

So this line passes through the point
which is the y-intercept. To graph this line, we'd need another point. So let set
:

So another point is:

Finally, we graph a line that passes through these two points:

This is shown in the figure below.

The distance between two points can be found using the Pythagorean Theorem...
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(-8-12)^2+(18-6)^2
d^2=400+144
d^2=544
d=√544 units
d=4√34 units
d≈23.3 units (to the nearest tenth of a unit)
