The options are;
A) b + c = 90
B) 90 + c = 180
C) b + c = 180
D) 42 + b = 150
Answer:
C) b + c = 180
Step-by-step explanation:
From angle theorems, we know that sum of angles on a straight line is 180°
Now, c and 42° form a straight line.
Thus;
c + 42 = 180°
c = 180 - 42
c = 138°
Similarly b and c form a straight line and so;
b + c = 180°
From the given options, the only correct one is Option C.
We are given
Ronaldo delivers the papers at the rate of 6 papers in 24 minutes
so, number of papers =6 in time =24 minutes
so, firstly we can find rate
rate = ( number of papers)/( time taken)

now, we can find times
Time for 56 papers:
we are given
number of papers =56
rate is

now, we can find time



Time for 41 papers:
we are given
number of papers =41
rate is

now, we can find time



now, we can find time difference

so, we can plug values

Answer: 21.4
Step-by-step explanation:
Area of a triangle = (1.7 * 2)/2=1.7 m2
Area of a rectangle = 3 * 2 = 6 m2
3 * 6 = 18 m2 2 * 1.7 = 3.4 m2
the total area is 18 + 3.4 = 21.4 m2
