Answer:
c.10 square units
Step-by-step explanation:
Area of Triangle = 1/2(x1(y2−y3)+x2(y3−y1)+x3(y1−y2))
substitute the coordinates in the formula and take modulus ( so that the answer becomes positive )
I hope you understood , cheers mate !!
SUM OF ALL ANGLES OF A TRIANGLE =180
THEREFORE,
X+8+2X-3+6X-5=180
9X=180
X=20.
THEREFORE,<J=X+8=20+8=28
<K=6X-5=6*20-5=120-5=115
<L=2X-3=2*20-3=40-3=37.
1/2 s + 3/4 s + 1/4 s + 4
((2+3+1)/4)s +4
6/4 s + 4
3/2 s + 4
......
20:24
=5:6
A is 5:6
