Answer:
hey
Step-by-step explanation:
the answer is 5
154 degrees; when you add up the two angles you get 154 subtract that from 180 which is the sum of a triangle. You should get 26 for the third angle of the triangle. when you extend the segment if MH you form an X the acute angle of the X are 26 to find H you subtract 26 from 180 since a straight line is 180 and you get 154 for the abtuse angles which is also H

Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
