Use the following diagrams for questions 3 and 4 questions in picture

The answer is x=84

Step-by-step explanation:

The lines p and f are parallel and t is the transverse line

Here the corresponding angles are equal

i.e. the angle made by the transverse line with each of the parallel line

is equal

So in fig 1 -60

fig 2 -124

fig 3 -135

So x=84 [corresponding angles are equal]

84°

corresponding angles are equal.

Step-by-step explanation:

Question 3

The angles in the four diagrams shown are called corresponding angles. Corresponding angles are the same.

For our case above, the angle x corresponds to 84°.

Question 4.

Looking at the 4 diagrams, we have a pair of parallel line and a transverse.

The angles formed between the parallel line and the transverse for the first 3 diagrams are the same.

Based on this observation, I can say that the value of x is 84°. The angles are corresponding and corresponding angles are equal.

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.
