Answer:
0.8
Step-by-step explanation:
I Dont know 3, 4, 5 so I am going to just use the normal formula
a^2 + b^2 = c^2
0.6^2 + b^2 = 1^2
0.36 + b^2 = 1
b^2 = 0.64
b= 0.8
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>
