Answer:
It’s so easy to put exercise and activity to the bottom of your long to-do list. But being active is one of the most important things you can do, each day if you can, for good health.
While you may not be able to reduce time for other commitments, you might try to squeeze short bursts of activity into your busy life. Every bit helps.
You’re likely to have more success at including exercise into your life if you:
consult an Australian registered exercise professional (AusREP), accredited exercise physiologist or physiotherapist for advice on exercising safely and avoiding injury
choose activities that appeal to you
track your progress (and feel good about your achievements!)
learn an exercise or two you can do quickly and easily for days when you’re feeling particularly time-poor
devise a realistic exercise plan for your lifestyle and routine.
Remember, any exercise is better than none, and you can make it quick and easy if that’s all the time you have. By making time for activity everyday you’ll be setting yourself up for better long-term health.
We know that AOB will be a straight line only if the adjacent angles form a linear pair. ∠BOC + ∠AOC = 180o By substituting the values we get (4x – 36)o + (3x + 20)o = 180o 4x – 36o + 3x + 20o = 180o On further calculation we get 7x = 180o – 20o + 36o 7x = 196o By division we get x = 196/7 x = 28 Therefore, the value of x is 28.
