Vertices of the triangle:
<span>J (-2,1), K (4,3), and L (-2,-5) </span>
<span>Area of triangle: 18
or
</span>determinant=
<span>4,3,1 </span>
<span>-2,1,1 </span>
<span>-2,-5,1 </span>
<span>determinant= 4(1+5)-3(-2+2)+1(10+2) = 36 </span>
<span>A = determinant/2
</span>36/2=18
Notice that one side is vertical. Use that side as base.
<span>Area is 18.</span>
It’s D!!! Pyramid pls give brainliest it can’t be triangle cause triangles r 2D and pyramids are 3R

Answer:
46
Step-by-step explanation:
Two tangents to a circle from the same external point are congruent.
There are 4 pairs of congruent tangents in the figure.
Starting at the lower left and going clockwise gives
perimeter = 6 + 6 + 8 + 8 + 4 + 4 + 5 + 5 = 46 units
