An appliance repairman charges $35 for a house call and $30 per hour. The
cost of a house call and repair job
came to $125.
Course 3, Lesson 2-3

3 hours.

Step-by-step explanation:

I'm assuming that you are asking how many hours the repairman worked in this problem. To find the solution, use the equation $125=35+ 30x.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
