Question

SOLVE FOR X PLEASEEE HELP​

Answer 1

2.28

Explanation:

∆ABC~∆ADE

So, x/4=4/7

7x=16

x=16/7

x=2.28

Answer 2

2.2857

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
