X=2.4 Y=6
This is an equilateral triangle since 2 angles are already 60 degrees
one of the sides is 10 so that means all other sides must also equal 10
For x, you make the equation equal to 10, since that’s the value it must equal to
10x-14=10
Add 14 to both sides to leave the x alone
10x=24
Divide both sides by 10 to leave x alone
x=2.4
For Y, you also make the y equal to 10
2y-2=10
Add 2 to both sides to leave the y alone
2y=12
Divide both sides by 2 to leave y alone
y=6
