Question

Help me please please

Answer 1

see image

basically, you have to find the side lengths using the distance between points formula

`\sqrt{|y_2-y_1|^2+|x_2-x_1|^2`

then you need the law of sines to find one of the angles

solving for the angle that formula is;

`Y (gamma ) = cos^-1((a^2+b^ 2-c^2)/(2ab))`

Y, or gamma, is the angle opposite C.

then i plugged it into the formula area = 1/2 a * b * sin (C)

all the math is in the picture

hope this helps,
