Answer: x=-1.9
Step-by-step explanation:


-18 on both sides

divide 7 on both sides

Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
Answer: g > -1
Step-by-step explanation: isolate by dividing each side that dosent contain a variable
Answer:
x=-3y/11 , y=-11x/3
