Tom is incorrect
He keeps getting the same number of 1:6 on each roll.
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.
Answer:
C. 108
Step-by-step explanation:
The angles are known as same-side interior angles. They are supplementary angles so their sum is 180°.

The rise of -7 means that there is 7 less. The fall of 7 would mean that it is also 7 less. So, yes. They are both the same thing.
