Find the measure of the exterior angle

pls, is urgent
tysm<3

134 degrees

Step-by-step explanation:

a triange has a total of 180 degrees

this means the 2 angles in the are equal to

180-(last angle)=x+102

the exterior angle is also 180-(last angle)

thus you can set the two equal to each other

(4x+6)=x+102

move 6 and x

3x=96

x=32

plug in

(4(32)+6)=134

to check

180-134=46(last angle of the triangle)

32+102+46=180 (true)

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.
