Answer:
Substitute different values of x in y=3x and get corresponding y coordinates.
Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)
Substitute different values of x in y=3x and get corresponding y coordinates.Such as (0,0),(1,3),(2,6),(−1,−3),(−2,−6)Now, when x=−2 then y=−6 .
The value of the integral 3ydx+2xdy using Green's theorem be - xy
The value of be -xy
<h3>What is Green's theorem?</h3>
Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C.
If M and N are functions of (x, y) defined on an open region containing D and having continuous partial derivatives there, then
=
Using green's theorem, we have
= ............................... (1)
Here = differentiation of function N w.r.t. x
= differentiation of function M w.r.t. y
Given function is: 3ydx + 2xdy
On comparing with equation (1), we get
M = 3y, N = 2x
Now, =
=
= 2
and, =
=
= 3
Now using Green's theorem
=
=
=
=
The value of be -xy.

Answer:
Option B) Acute
Step-by-step explanation:
we know that
if a triangle contains an obtuse angle, then the other two angles must be acute.
<em><u>Verify</u></em>
The sum of the interior angles of a triangle must be equal to 180 degrees
in the triangle of the figure
113°+15°+x°=180°
Solve for x
118°+x°=180°
x=180°-118°=62°
62° < 90°
therefore
The angle x is an acute angle
