Answer 1

y = mx + c
we have y = √3x - 4
compare both side
m = √3. where m means slope and slope = tan A .
so tan A = √ 3
SO A = 60 DEGREE

Answer 2

Slope of given line m=square root 3
Then tan A=square root 3
A=60 degrees 
This is angle made by the line with x-axis
Therefore the angle made by the line with y-axis is 30 degrees.



Hope will help u. All the best for ur board exam....
