Given
A triangle.
with vertices at (−2, 1) , (2, 1) , and (3, 4)
Find out the area of a triangle.
To proof
Formula

As given the vertices at (−2, 1) , (2, 1) , and (3, 4)
put in the above equation
we get
![= \frac{1}{2} [-2(1-4)+ 2 (4-1) + 3 ( 1-1) ]](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5B-2%281-4%29%2B%202%20%284-1%29%20%2B%203%20%28%201-1%29%20%5D)
solving
![= \frac{1}{2} [6 + 6]](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5B6%20%2B%206%5D)
thus
![=\frac{1}{2} [12]](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%20%5B12%5D)
area of the triangle is 6 units².
Hence proved
Answer: =80/11
Step-by-step explanation:x=80-10x
We move all terms to the left:
x-(80-10x)=0
We add all the numbers together, and all the variables
x-(-10x+80)=0
We get rid of parentheses
x+10x-80=0
We add all the numbers together, and all the variables
11x-80=0
We move all terms containing x to the left, all other terms to the right
11x=80
x=80/11
x=7+3/11

Determine the equation to find x
First, is to complete the angles of the triangle (ABC and ACB)
--- angle on a straight line

Collect like terms


--- angles in a triangle

Collect like terms


Apply sine rule

In this case:

This gives:

Answer:
x = -7
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (&Roots)
Multiplications
Divisions
Additions
Subtractions

First, add 6 to both sides of the equation:
-5x - 6 = 29
-5x - 6 (+6) = 29 (+6)
-5x = 29 + 6
-5x = 35
Next, divide -5 from both sides of the equation:
(-5x)/-5 = (35)/-5
x = 35/-5
x = -7
-7 is your answer for x.
