Find the value of each numbered angle.

Step-by-step explanation:

∠1 + 74 = 180   (linear pair)

∠1 = 180-74

∠1 = 106

∠2 + 90 = 180 {linear pair}

∠2 = 180 - 90

∠2 = 90

∠3 +116 = 180 {linear pair}

∠3 = 180 -116

∠3 = 64

∠4 + 65 = 180  

∠4 = 180 - 65

∠4 = 115

Sum of all angles of polygon = (n-2)*180= (5-2)*180

= 3 * 180 = 540

∠1 + ∠2 +∠3 + ∠ 4 + ∠5 = 540

106 + 90 + 64 + 115 + ∠5 = 540

375 + ∠5 = 540

∠5 = 540 - 375

∠5 = 165

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
