Find value of x (show all work)

15. 97° .

16. 5° .

17. 24°

Step-by-step explanation:

15. x - 52 + x - 75 = 360 - 293

2x - 127 = 67

2x = 67 + 127

2x = 194

x = 194/2 = 97°.

16. 4x + 15 = 5 + 6x

6x - 4x = 15 - 5

2x = 10

x = 5°.

17. x + 17 + 2x + 1 = 90

3x + 18 = 90

3x = 90 - 18

3x = 72

x = 72/3 = 24°.

15) 97

16) 16

17) 24

Step-by-step explanation:

15) (x-75) + (x-52)+ 293=360

x - 75 + x - 52 + 293 = 360

2x - 127 + 293 = 360

2x + 166 = 360

        2x  = 194           [Subtract 166 from both side]

          x  = 97             [Divide by 2 from both side]

16) (4x+15)+(5+6x)=180         The angle of a straight line is 180.

4x + 15 + 5 + 6x = 180

10x + 20 = 180

        10x = 160            [Subtract 20 from both side]

            x = 16               [Divide by 10 from both side]

17) (x+17)+(2x+1)= 90               These two angle combined equal to 90.

x + 17 + 2x + 1 = 90

3x + 18 = 90          

3x = 72                         [Subtract 18 from both side]

x = 24                           [Divide by 3 from both side]
