Question

The digits of a three-digit natural number are in A.P. and their sum is 18. The number
obtained by reversing the digits is 594 less than the original number. Find the original
number.​

Answer 1

Answer:

369

Step-by-step explanation:

a+(a+d)+(a+2d)=18

a+d=6 hence one no. is 6

hence A.P. will form from no. 369 and its reverse is 963 and

963-369=594

hence original no. is 369.

Answer 2

Answer:

Step-by-step explanation:

Answer:

X=130°,y=30°

Step-by-step explanation:

As l || m || n

Then angle 1=50°

Therefore angle 1 is equal to angle 2 = 50° (co-interior angles)

Then why linear pair

Angle x + angle 2 =180degree

x+50°=180°

x=180°-50°

x=130°

2. Angle y is equal to angle 3 equals to 30 degree (co -interior angles)
