First you have to find the angle B (check attachment)

Then you can find the last angle inside the triangle, which I'll call C

Now you can find angle A

Step-by-step explanation:
given,
x1= 1 , x2= 7 , m1= 3
y1= 4 , y2= 1 , m2= 1
x=?
y=?
using section formula
x= (m2.x1 + m1.x2)/m1 + m2
x= find yourself
y= (m2.y1 + m1.y2) / m1 + m2
y= find yourself
