Answer:

x=3, y= - 2

Step-by-step explanation:

4x + 3y = 6

x-3y= 9

x=9+3y

4.(9+3y)+3y=6

36+12y+3y=6

15y = - 30

y = - 2

=> x= 9+3y

x= 9+ 3.(- 2)

x= 3

mojhsa [17]

Answer:

about 16°

Step-by-step explanation:

Make sure your calculator is in degree mode.

Drawing the right triangle, we see that the shorter leg is 34 meters, and the longer leg is 122 meters. So the angle of elevation is:

$\alpha = { \tan }^{ - 1} \frac{34}{122} = 15.57$
