Step-by-step explanation:
13).
This is an equilateral triangle.
We see that all 3 angles are equal, so all sides are equal also.
So 2x - 6 = 10
2x = 16
x = 8.
Answer:
Step-by-step explanation:
If I am correct the triangle has equal sides and I think you're trying to find x. So 10=2x-6 and then solve. Once you get the x (assuming you know how to get it) plug it into the equation (of 2x-6) and get the remaining number. (For example: if x=2 then 2x2-6, then you solve: 2x2=4 4-6=-2) I don't know if you want the answer though...
(depends if you want x or the rest)
