Answer: 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]
