Answer:
True
Step-by-step explanation:
AD=DC (S)
Angle BAD = Angle BCD (A)
BD is similar side (S)
Therefore it is true because of SAS.
Because this is 4 sided, it is 360°(in total)
The shape is parallel on 2 sides(shown by the red arrows), so (5x)° = 90°
5x = 90
x = 18°
You can add all the angles together and set it equal to 360°
90° + (5x)° + (5(y+11))° + (4y-10)° = 360°
Since you know 5x is 90°, you can plug it in
90° + 90° + (5(y+11))° + (4y-10)° = 360°
180° + (5(y+11))° + (4y-10)° = 360° Subtract 180° on both sides
(5(y+11))° + (4y-10)° = 180°
5y + 55° + 4y - 10° = 180°
9y + 45° = 180°
9y = 135°
y = 15°
x = 18°, y = 15°

there is no picture??????????
The William's family used the sprinklers for 59 hours.
Because it used 25L per hour so 25/1 is 25 so then you multiply 1475 by 25 and you get 59
= used sprinklers for 59 hours.
The Taylor family used the sprinklers for 73.75 hours.
Because it used 20L per hour so 20/1 is 20 then you multiply 1475 by 20 and you get 73.75
= Used sprinklers for 73.75 hours.
