Can someone help me with this.

Step-by-step explanation:

∠VUD + ∠WUV = 180°    {Straight line}

86 + ∠WUV = 180

∠WUV = 180 - 86

∠WUV = 94°

Sum of all angles of triangle = 180°

∠VUW + ∠UWV + ∠WVU = 180

94 + x + 8 + 9x - 2 = 180

10x + 100 = 180

10x = 180 - 100

10x = 80

x = 80/10

x = 8

∠W = 9x - 2 = 9*8 -2 = 72 -2

∠W  = 70°

m< W = 70

Step-by-step explanation:

First you have to find what x equals

To do that find all the angles inside triangle VWU

We can find angle  U by subtracting 180- 86

= 94

SO now add up the variables from inside the triangle

x + 8 + 94 + 9x - 2 = 180

Add up like terms

10x + 100 = 180

Isolate 10x

10x + 100-100 = 180-100

10x = 80

Divide 10 in each side

x= 8

Now the question is to find m<W

We already know the x so just put it in the angle

9(8) - 2

72 - 2

=70

To make sure it is correct find all the angles and add them all together to make sure it adds up to 180

70 + 94 + (8+8)

=180

idk bring the function back   im not smart

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.
