Me i don’t understand how to do this

Step-by-step explanation:

Given : RS and UV are the parallel lines.

m∠STV = 108°

m∠RST = 74°

a) We have to find the measure of ∠TVU.

Since RS and UV are the parallel lines and SU is the transverse.

Therefore, m∠RST = m∠TUV [alternate angles]

m∠TUV = 74°

m∠STV + m∠UTV = 180° [Supplementary angles]

108° + m∠UTV = 180°

m∠UTV = 180° - 108°

m∠UTV = 72°

Now m∠UTV + m∠TVU + m∠TUV = 180° [Sum of the angles of a triangle = 180°]

72 + m∠TVU + 74= 180

m∠TVU + 146° = 180°

m∠TVU = 180° - 146°

m∠TVU = 34°

Therefore, measure of angle TVU is 34°

b). In the triangles RST and TUV,

∠RTS ≅ ∠UTV [Vertically opposite angles]

RS and UV are the parallel lines and line RV is the transverse.

Therefore, ∠SRT ≅ ∠UVT [Alternate angles]

RS and UV are the parallel lines and line SU is the transverse.

Therefore ∠RST ≅ ∠TUV [Alternate angles]

Since all corresponding angles of both the triangles are equal. Therefore, triangles RST and TUV will be similar.

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.
