I looked it up, it says eq triangles have 3 sides. An isos triangle is one with 2 equal sides. Every eq triangle is isos, but not every isos triangle is equilateral. I think the statement in the photo is true.
Answer:

Step-by-step explanation:
We have a figure given in the shape of a square with a diagonal (x) passing from one edge to another. We need to find the measure of its diagonal if the side of the square is
units.
We know that, a square has all equal sides. Then, all the sides of the square will be equal to
units.
Now, let's find the diagonal.
To find the diagonal of a sqaure from one of its sides, we need to know the formula ⟶ Diagonal = side
.
By using this formula,

→ The diagonal of the square = 2√5 units.

.50 × N = 30
Divide both sides by .50
N = 60.
