A = 45
b = 75
c = 37
d = 137

a-
whenever the angle is shaped like that they are equal i forgot the actual property name though

b-
and the known angles up (so 45 and 60) then subtract 105 from 180 to get 75 which is the answer

c-
add the known angles then subtract from 180 (so add 75 and 68) then u should get 37

d-
add all known angles then subtract from 180 (so add 37 and 100) you should get 43
then ur gonna subtract 43 from 180 to get the answer which is 137

Use the Green's Theorem to calculate the work done by the field [ F (x, y) = -3y^5 i + 5y^2x^3 j ] to move a particle along the
lianna [129]
\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\iint_R\left(\frac{\partial(5y^2x^3)}{\partial x}-\frac{\partial(-3y^5)}{\partial y}\right)\,\mathrm dx\,\mathrm dy

\dfrac{\partial(5y^2x^3)}{\partial x}=15y^2x^2
\dfrac{\partial(-3y^5)}{\partial y}=-15y^2

=\displaystyle\int_{x=-2}^{x=2}\int_{y=-\sqrt{4-x^2}}^{y=\sqrt{4-x^2}}15y^2(x^2+1)\,\mathrm dy\,\mathrm dx

Converting to polar coordinates, the integral is equivalent to

=\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=2}15r^3\sin^2\theta(r^2\cos^2\theta+1)\,\mathrm dr\,\mathrm d\theta
=\displaystyle15\int_0^{2\pi}\int_0^2\left(\frac{r^5}4\sin^22\theta+r^3\sin^2\theta\right)\,\mathrm dr\,\mathrm d\theta
=\displaystyle\frac{15}4\left(\int_0^2r^5\,\mathrm dr\right)\left(\int_0^{2\pi}\sin^22\theta\,\mathrm d\theta\right)+15\left(\int_0^2r^3\,\mathrm dr\right)\left(\int_0^{2\pi}\sin^2\theta\,\mathrm d\theta\right)
=100\pi
