Answer:
it is an example of an expression
Step-by-step explanation:
it is an example of an expression because it is asking a question without an equal sign. so its not a question, but an expression
X=70, y=55
The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.
Then use the triangle angle sum theorem and set the equation to 180.
55+55+x=180
110+x=180
x=70
The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
