i think the answer is the 3rd one
plz give me brainliest
a. Parameterize
by

with
.
b/c. The line integral of
over
is




d. Notice that we can write the line integral as

By Green's theorem, the line integral is equivalent to

where
is the triangle bounded by
, and this integral is simply twice the area of
.
is a right triangle with legs 2 and 5, so its area is 5 and the integral's value is 10.
The triangle drawn in the question shows a small single line drawn across two sides of the triangle.
This means that those two sides are equal in length.
Hence, the triangle is an isosceles triangle.
In isosceles triangles, the angles opposite to the equal sides are also equal.
Hence, we know that the two angles other than x is 56°.
The sum of the interior angles of a triangle is 180°
x + 56 + 56 = 180
x = 180 - 56 - 56
x = 180 - 112
x = 68°
Hence, the answer is A.
I believe it’s 2% if it’s wrong sorry
M = Y / X
m = [1 - (-2) ] / [2 - (-2)]
m = (1+2) / (2+2)
m = 3 / 4
Using (2,1)
y - yo = m (x-xo)
y - 1 = 3/4 (x-2)
Or
(-2,-2)
y + 2 = 3/4 (x+2)
D and F
