Hi there! :)
<u>Answer:</u>
x = -2
Step-by-step explanation:
<u>5</u> - 3x = 11
Subtract "5" from each side of the equation → 11 - 5 = 6
<u>-3</u>x = 6
Divide each side of the equation by "-3" → 6 ÷ -3 = -2
<u>x = -2</u>
There you go! I really hope this helped, if there's anything just let me know! :)
In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.
It is logical therefore, that the first step in proving this is by using the definition of a triangle.
