What is the area of triangle ABC?
miskamm [114]

Answer:

<h2>7 square units</h2>

Step-by-step explanation:

As you can observe in the image attached, we know the coordinates of each vertex of the triangle.

To find the area using only its vertex coordinates, we need to use the following formula

A=\frac{1}{2}[x_{1}(y_{2} -y_{3}+x_{2}(y_{3} -y_{1} )+x_{3}(y_{1}-y_{2}  )   )

Where the coordinates are

A(1,1)\\B(4,0)\\C(3,5)

Replacing coordinates, we have

A=\frac{1}{2}[1(0 -5)+4(5 -1 )+3(1-0  )  ]\\A=\frac{1}{2} [-5+16+3]=\frac{1}{2}(14)\\ A=7

Therefore, the area of the triangle is 7 square units. So, the right answer is the second choice.

I reached into my pocket and found that I have only dimes n nickels. I have 2.00. I have 11 coins. How many dimes do I have?
sdas [7]
This is not possible,  because if you had 11 coins,  then not even 11 dimes will cover it,  because 11*10 is 110,  or $1.10
