In the given figure, find the value of x and y ?

In triangle ADC

Now,

We know that, Sum of all interior angles of a triangle is supplementary.

Thus,

∠ADC + ∠DAC + ∠ACD = 180°

⇛ 40° + 107° + x° = 280°

⇛ 147° + x = 180°

⇛ x = 33°

Now, ACE is a line.

So,

∠ACD + ∠DCB + ∠BCE = 180°

⇛ x + 65° + y = 180°

⇛ 33° + 65° + y = 180°

⇛ 98° + y = 180°

⇛ y = 180° - 98°

⇛ y = 82°

final answer is : )

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
