Awire lies along the piecewise linear curve extending from the point (4,3) to the point (19,6) to the point (19,9). if the density of the wire is given by rho(x, y)=4xy+7xrho(x, y)=4xy+7x, use a line integral to find the mass of the wire.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
