Answer:
Hence the correct option is the last one . The triangle is an obtuse angled triangle.
Step-by-step explanation:
i) the sum of any two sides added together is greater than the third side hence this is a triangle.
ii) it is<em><u> not</u></em> a right angled triangle as
and 
iii) the triangle is not acute from ii) above
iv) the triangle is an obtuse triangle from ii) above.

Answer:
y = -3x + 5
Step-by-step explanation:
(y2-y1)/(x2-x1)
Plug coordinates into that
Then plug one of the coordinates into y = -3x+b to get b
Answer:
Step-by-step explanation:
From the first image attached below, we will see the sketch of the curve x = y² & x = 2y
In the picture connected underneath, the concealed locale(shaded region) is bounded by the given curves. Now, we discover the marks of the crossing point of the curves. These curves will cross, when:

Thus, the shaded region fall within the interval 0 ≤ y ≤ 2
Now, from the subsequent picture appended we sketch the solid acquired by turning the concealed region about the y-axis.
For the cross-sectional area of the washer:

Finally, the volume of (solid) is:
