Answer:
D
Step-by-step explanation:
You can put the points in as the x and y values. 12(2)-(-1)=25 and 9(2)+(-1)=17
You X to the second power.. 4 to the second power is 16 and 16-16=0 so x=4
Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
