Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
Not exactly sure if I’m right but
1. $56 < $60
2. $60 - $36 = $24/4 hours = 6.
36+24 = 60, we want to use LESS than 60 so we use see how much it’ll take to spend 5 hours for parking.
5 x $4 = $20.
$36 + $20 = $56
I’m not exactly sure though...
