Answer 1

Answer:

sorry, but I can tell you only 11th answer...

Step-by-step explanation:

11) We know that there are 3 sides of a triangle

and in equilateral triangle the 3 sides x, y, z are equal to each other i.e. x=y=z

and we also know that the sum of all angles of triangle is 180°.

so, x+x+x=180

3x=180

x=180/3

x=60

thus, we say that each angle of a triangle is of 60°.

I hope you are satisfied with the answer..
