Answer:
The answer is 1
Step-by-step explanation:
I promise you
A=5i+2j
B=2i-3j
C=-8i+3j
we find the vectors of AB, BC & AC:
AB=(2-5)i+(-3-2)j=-3i-5j
BC=(-8-2)i+(3-(-3))j=-10i+6j
AC=(-8-5)i+(3-2)j=-13i+j
now if the dot product of two of these vectors result in zero, it means that those vectors (representing the triangle sides) are perpendicular to each other (which means triangle ABC is a right-angled triangle)
let's try:
AB.BC=(-3)(-10)+(-5)(6)=30-30=0
thus the triangle ABC is a right-angled triangle.
X=2y+11 and 4x+3y=11 so choose one of them. I choose x=2y+11 and solve it like this 4(2y+11)+3y=11
8y+44+3y=11
11y=-33
y=-3
