Answer: 12/-4= -3. -12/4=-3. -(12/4)= -3
Step-by-step explanation: All equal -3 just divide all of them to get the answer.
7 and 9/10
Working;
10 goes into 70 7 times. The remainder is 9.
The reasons would be:
alternate interior angles
vertical angles
AAA (all angles are congruent)
Since we know that the two line segments are parallel, this means that BC is a transversal. Using that knowledge with the position of ABE and DCE, we see these are alternate interior angles.
AEB and DEC are vertical angles, since they share only a vertex.
This gives us 3 congruent angles, so the triangles must be similar.
