Question

Help idk how to solve this

Answer 1

`answer \\ = 4 \\ solution \\ to \: find \: the \: value \: of \: x \\ in \: an \: equilateral \: triangle \: all \: interior \\ angles \: are \: equal \: and \: measures \: 60 \: \\ degree. \\ 10x + 20 = 60 \\ or \: 10x = 60 - 20 \\ or \: 10x = 40 \\ or \: x = (40)/(10) \\ x = 4 \\ hope \: it \: helps`

Answer 2

`x = 4`

Explanation:

in a equilateral triangle all the interior angles are equal and measure 60 degrees,

will solve now,

`10x + 20 = 60 \\ 10x = 60 - 20 \\ 10x = 40 \\ (10x)/(10) = (40)/(10) \\ x = 4`

hope this helps
