Find the value of x
please help

19. x = 66

20. x = 10

21. x = 9

Step-by-step explanation:

19. 133 and (x - 19) are supplementary angles, meaning that the sum of them is 180. So:

180 = 133 + (x - 19)

47 = (x - 19)

66 = x

20. the two angles are complementary, meaning that they add up to 90 degrees (as shown by the red square in the corner). So:

90 = 63 + (2x + 7)

27 = 2x + 7

20 = 2x

10 = x

21. the two angles are vertical angles, meaning that they equal each other. So:

59 = (6x + 5)

54 = 6x

x = 9

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
