Answer:
Yes, this triangle is a right triangle.
Step-by-step explanation:
Side AB lies on the x-axis and is thus horizontal. Side AC lies on the y-axis and is thus vertical. Sides AB and AC are therefore perpendicular to each other. This alone is enough info for us to conclude that this is a right triangle.
Side BC could be thought of as the hypotenuse.
It’s impossible because any number divided by 0 will always just be 0
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
