What is the solution to the system of equations? x+3y−z=6 4x−2y+2z=−10 6x+z=−12 (−3, 5, 6) (2, 1, −3) (0, −2, −12) (−4, 0, 12)

A) -3,5,6

Step-by-step explanation: Took the test

≈ 53.7° (Option 3)

Step-by-step explanation:

In the figure given above , the lengths of other two sides (excluding hypotenuse) are known to us. So , it would be convenient to use 'tan'.

Length of side opposite to angle 'x' = 15 cm

Length of side adjacent to angle 'x' = 11 cm

Using 'tan' formula - , lets solve this.

Using inverse tan function , lets find x.

≈ 53.74°
