I need help this makes no sense

m 10 is : 123

m 15 is: 123

m 16 is : 57

Step-by-step explanation:

To get m 10: I subtracted 180-57 and got 123.

To get m 15: I did not need to do anything for that because m10 and m15 are the opposite of each other which means there angle measure is the same.

To get m 16: I did not need to do anything because m9 is the opposite of m 16 which makes their angle measure the same.

7

step-by-step explanation:

the answer would be 7

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
