Answer:
43.5 unit^2.
Step-by-step explanation:
Area of the triangle
= 1/2 * base * height
= 1/2 * AB * AC.
AB = √ [(6-1)^2 + (6-8)^2] = √29
AC = √ [(8 - (-7))^2 + (1 - (-5)^2] = √261
So the area = 1/2 * √29 * √261
= 43.5
4
8/2=4
hope this helps :3
if it did pls mark brainliest
13
since the inside of a triangle is equal to 180
180-42-73=65
65/5=13 so 13 should be the answer.
four hundred thirty-two
