Find the values of x and y
PSYCHO15rus [73]

Hi there!

So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.


Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.

So the value of x is : 7


And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.

So the value of y° is : 60°


There you go! I really hope this helped, if there's anything just let me know! :)
