Answer:
yes it is possible to have a triangle with 8.8 cm, 8.0 cm and 8.8 cm.
Step-by-step explanation:
Condition on sides of triangle:
- The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
- It is not possible to have sum to be less than the length of the third side.
- A triangle with three given positive side lengths exists if and only if those side lengths satisfy the given condition
- Let a, b and c be three sides of triangle.

Here, we are given that a = 8.8 cm, b = 8.0 cm, c = 8.8 cm
We check for the triangular inequality:

Thus, yes it is possible to have a triangle with given measurements.
Answer:
x = 60
∘
Explanation:
As indicated by the markings, all the sides of this triangle are equal, and therefore all the angles of this triangle must be equal as well.
Let x be an angle,
so by the triangle sum theorem, we can say that:
3 x = 180
∘
x = 60
