Answer:
x=63
Step-by-step explanation:
Because we know that the total angle is a right angle (see the square in the top right of the problem), and 25 and x+2 constitute as the only two angles making up the total angle, we can say that 25 and x+2 are complementary, meaning they add up to 90 degrees. We can then write our equation as follows:
25 + (x+2) = 90
27+x=90
Subtract 27 from both sides
x=63
Find how many hours he does in a day and then divide that by the number of papers he delivers every day.
Answer:
opposite sides of a parallelogram are equal
2x+15=x+15
2x-x=15-15
x=0
