Answer:
No
Step-by-step explanation:
It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,
→ 11²+ 12² = 13²
→ 121 + 144 = 169
→ 265 ≠ 169
<h3>Hence the ∆ is not a right angled triangle </h3>
3x+y=4 (y=-3x+4)
Plug it in for y x+2(-3x+4)=-2
x=2
Plug in for x 2+2y=-2
y=-2
Solution: (2,-2)
