Answer:
115°
Step-by-step explanation:
The sum of angle measures of a pentagon is 540°, so your unknown angle can be found from ...
... 103° + 100° +110° +112° +unknown = 540°
... unknown = 540° -425° = 115° . . . . . . . . subtract 425° from both sides

<em>Angles of a polygon</em>
The external angles lf a convex polygon always sum to 360°. The sum of internal and external angles is, of course, 180°. So, an n-sided polygon has internal angle measures that sum to ...
... n×180° - 360° = 180°×(n -2)
Thus, a pentagon has internal angles that sum to ...
... 180°×(5 - 2) = 540°
The easiest way is if it doesn't need to be simplified. Multiply -2.105 by

. You get the fraction

. While this is technically the answer, you can simplify this down to

. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is

.

.
Well, the base and height would still be applicable (essentially, base is just width and height is just, uh, height,)
So basically the area of one triangle is 0.5(7*6), which is 21
The area of one triangle is option c., 21.
Use the equation for the volume of a cone to solve for the height:
