Answer:
2.2857
Step-by-step explanation:
To solve this I'm going to find Angle A
I have the adjacent and opposite side so using TOA is easiest
let a= angle
tan(a)=4/7
a=29.74488
Now that we have the angle A we can only look at triangle ABC
To solve for x we use TOA again
tan(29.74488)=x/4
4tan(29.74488)=x
x=2.2857
