PLEASE HELP ASAP!!!!!

Answer 1

Answer:

$\huge\boxed{\sf x = 20}$

Step-by-step explanation:

=> Since it is an equilateral (Having all angles and all sides equal)  triangle, so every angles will be equal to the other.

=> The sum of the measures of interior angles of triangle add up to 180 degrees.

So,

3x + 3x + 3x = 180

9x = 180

Divide both sides by 9

x = 20

$\rule[225]{225}{2}$

Hope this helped!
