Compare corresponding angles to decide if they are congruent. Since AB is horizontal and BC is vertical, ∠B is (select)
. Similarly, ∠E is
(select)
.

m∠B = m∠E =
°

By the Triangle Sum Theorem, m∠C is equal to
°.

By the Triangle Sum Theorem, m∠D is equal to
°.

So, ∠A
(select)
∠D, ∠B
(select)
∠E, and ∠C
(select)
∠F. The triangles have
(select)
of congruent corresponding angles.

AB is horizontal and its length is
units. BC is vertical and its length is
units.

By the Distance Formula, AC is .

DE is horizontal and its length is
units. EF is vertical and its length is
units.

By the Distance Formula, DF is .

So, AB ≅
(select)
, BC ≅
(select)
, and AC ≅
(select)
.

△ABC

Step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
