Answer:
x = 92.5°
Step-by-step explanation:
both are isosceles triangles, with two angles similar
2y + 110 = 180°
2y = 180-110
y = 70/2 = 35°
2z + 65 = 180
2z = 180-65
z = 115/2 = 57.5°
so total angle, x = 35 + 57.5 = 92.5°
For
|a|<b
assume
-b<a<b
so
add 5 to both side
|-2-8x|<66
assume
-66<-2-8x<66
add 2 to both sides
-64<-8x<68
divide everyboy by -8, don't forget to flip sign
8>x>-8.5
-8.5<x<8
the solution is all numbers between -8.5 and 8, not including -8.5 and 8
in interval notation: (-8.5,8)
or
S={x|-8.5<x<8}
