Answer:
Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.
Answer:
The amount paid by each house is $11.25
Step-by-step explanation:
Let the amount paid by each house is $K
Number of neighbors you worked for on Friday = 4
So the amount paid by all of them = 4K
Number of neighbors you worked for on Saturday = 5,
similarly amount paid = 5K
Number of neighbors you worked for on Sunday = 3,
here amount paid = 3K
Also, in total the amount paid = $135
So, Amount paid on {Friday + Saturday +Sunday} = Total Amount
or, 5K + 4K + 3K = $135
or, 12K = 135
⇒K =135/12 = $11.25
So, the amount paid by each house is $11.25
