10
Step-by-step explanation:
you can see it two ways 5×2 or 2×5 better to see it 5×2 cause it's simple 5 then 10 you just add more onto what's the number
Step-by-step explanation:
AB=OB-OA
AB=[4,-2]-[-4,6]
AB=[8,-8],|AB|=8units
BC=OC-OB
BC=[-6,-4]-[4,-2]
BC=[-10,-2],|BC|=√104
AC=OC-OA
AC=[-6,-4]-[-4,6]
AC=[-2,-10],|AC|=√104
d. Based on the lengths of the sides,the triangle is isosceles
The vertices of the attached triangle are
A(9, 0)
B(0, 4)
O(0, 0)The leg lengths of this triangle are 9 and 4 units. Its area can be computed using the formula for the area of a triangle.
A = (1/2)(9)(4) = 18 . . . . square units
Since the result of this calculation is 18 square units, we know it has the correct area.
_____
The area measuring tool in the drawing app also shows the area to be 18.
