What angle relationship describes angles BCE and CED?
Alternate interior angles
Alternate exterior angles
Corresponding angles
Same-side interior angles

alternate interior angles

Step-by-step explanation:

You are correct. The answer is choice A) Alternate Interior Angles.

I recommend using a marker to highlight the angles in question. These angles are inside, or interior, of the parallel lines. They are also on alternating sides of the transversal line. So that's why we consider them alternate interior angles. Because the lines are parallel, the alternate interior angles are congruent. In this case, both are 30 degrees.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

[2, 2.5)

(2.5, 3]

i think its these two not sure [2, 2.5)
