An isosceles triangle is one having two of its sides equal.
Step-by-step explanation:

Thus first option is the correct answer.
Answer:
The Y-Intercept of a line is the point where a line's graph intersects (crosses) the Y-axis.
A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0,3).
A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0,-4).

Answer:
70 degrees
Step-by-step explanation:
The adjacent angles in a parallelogram are supplementary and add to 180 degrees
∠CDE+∠DEF=180
We know that ∠CDE is 110 degrees, so we can substitute that in
∠CDE+∠DEF=180
110+∠DEF=180
Subtract 110 from both sides
∠DEF= 70
So, ∠E is 70 degrees
