Question

What does X equal how do I get it?

Answer 1

equilateral because of those hash marks

so

14.1=y-7
add 7 to both sides
21.1=y


and, all internal angles of equilaterl are 60 degrees
3x=60
divide by 3
x=20 degrees

y=21.1ft
x=20 degrees

Answer 2

x=20 because it's an equilateral triangle all the angles are 60 deg
