Answer:

x = 3

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle:

15x + 5 + 22x + 4 = 120 add like terms

37x + 9 = 120 subtract 9 from both sides

37x = 111 divide both side by 37

x = 3 and to find the angles replace x with 3 in given expressions

Kitty [74]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y> \frac{1}{4}x+6 ------>inequality A

The solution of the inequality A is the shaded area above the dashed line y=\frac{1}{4}x+6

The y-intercept of the dashed line is (0,6)

The x-intercept of the dashed line is (-24,0)

The slope of the dashed line is positive m=1/4

y> 2x-1 ------>inequality B

The solution of the inequality B is the shaded area above the dashed line y=2x-1

The y-intercept of the dashed line is (0,-1)

The x-intercept of the dashed line is (0.5,0)

The slope of the dashed line is positive m=2

The solution of the system of inequalities is the shaded area between the two dashed lines

using a graphing tool

see the attached figure
