It can be b), c) and d).

b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.

c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.

d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.

a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)

Given a pair parallel lines cut by a transversal same interior angles are supplementary?
makkiz [27]
If 2 parallel lines are cut by a transversal, then the alternate exterior angles are congruent. If 2 parallel lines are cut by a transversal, then the same side interior angles are supplementary. A line that intersects 2 coplanar lines at 2 different points.

A parabola has the focus at (4,6) and the directrix of Y equals -6
DerKrebs [107]

Answer:

y = (x-4)²

Step-by-step explanation:

vertex (h , k)

h = 4   .... axis of symmetry

k = (6 + -6) / 2 = 0  .... midpoint of focus and directrix

equation of parabola: y = (x-4)²       y = (x-h)² + k
