Answer:

#here we input value from where program find the even value start_value = int (input("Type a start number you want to find even number of:")) #here we input value till where program find the even value stop_value = int (input("Type an end value to which you want to find even number of:")) #this is loop use to find even number from starting value to end integer for even_num in range(start_value,stop_value,2): #here we print all even numbers print(even_num)

Question:

A ladder which is inclined into the wall is 10 m long, and makes an angle of 45 degree with the ground. A ladder reaches 7 m high on the wall and the distance between ground and the foot of the wall is 11 m. Find the angle the ladder make with the wall.

Answer:

Suppose, inclined wall be hypotenuse (h), a ladder reaching at some point of the wall be perpendicular (p), a distance between a foot of a ladder and wall be base (b), an angle between foot of a ladder and the wall be (ɵ) From question, it is given that, h = 10 m, p = 7 m, b = 11 m, and ɵ = 45 degree. Then, to find the remaining angle, We can use, (180 = 90 + 45 +x) degree, where 180 degree is the total angle of a triangle, 90 degree is the right angle between point of the wall and the ground, 45 degree is the given angle, x degree is the angle we need to find, according to the question. Therefore, by calculation, x = 55 degree.

Question:

A and B are two finite sets, where n(A) = 15, n(B) = 14 and n(A∪B) = 7. Find the value of union of A and B.

Answer:

Given, n(A) = 15, n(B) = 14, n(A∪B) = 7. Now, To find, union of A and B, i.e., n(A∩B) We have, n(A∩B) = n(A) + n(B) - n(A∪B) = 15 + 14 - 7 =22 Hence, the value of union of A and B is 22, respectively.
