Answer:

Step-by-step explanation:

using sin formula

let third angle=α

\frac{sin~\alpha }{7.9} =\frac{sin 18}{8.4} \\sin \alpha=\frac{7.9}{8.4} \times sin~18\\\alpha=sin^{-1} (\frac{7.9}{8.4} \times sin18)\\\approx 16 ^\circ 54'\\\theta=180-(18+16^\circ 54')\\=180-34^\circ54'\\=145^\circ 06'

Answer:

The equation is y = 3/5x - 6

Step-by-step explanation:

First we have to find the slope of the line. In order to do so, solve the first equation for y.

3x - 5y = 7

-5y = -3x + 7

y = 3/5x + 7/-5

This gives us a slope of 3/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.

y - y1 = m(x - x1)

y - -6 = 3/5(x - 0)

y + 6 = 3/5x

y = 3/5x - 6
