What is the formula to find the area of a triangle
2 answers:
Answer:
(1) As a simple definition, a triangle is a two-dimensional figure that has 3 sides (and 3 angles as well).
(2) A triangle as shown in attached picture has the area that is typical calculated by the multiplication of half of base and height.
A = (1/2) x Base x Height
<em>Base can be a particular side of triangle</em>
<em>Height is the perpendicular line segment between the opposite vertex of selected base and that base.</em>

Answer:
C. -11,325
Step-by-step explanation:
- To know the answer, is convenient to replace some values of "n" in the sum
.
- The result would appear after adding up every value of the expression
- When n=1, the expression takes the value of (-1):
.
- When n=2, the expression takes the value of (-2):
.
- Following this way, for every n, we will obtain -n, then, the sum will be:
. This sum can actually be expressed as
, which is the result of solving the initial expression of the sum
.
- Finally, the sum of n=-1 to n=-150 equals -11,325.
