Answer: 45
Step-by-step explanation:
The total degrees in a circle is 360.
The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.
so 90 + x + 3x = 90 + 4x = total
90 + 4x = 360
4x = 180
x = 45 degrees
C
first set up an equation
$52+8n ≥ 144
bacause she can spend 144 or less
solve 144-52=92
92/8=11.5
