A part of compound wall is 36m long,4m high and 30cm wide. It contain s two windows each od 2m × 1.5m and a door of size 2m×3m. 1) find the number of bricks each of18cm ×10cm×8cm reqiired for for the construction of the wall
2) find the cost of bricks at Rs17,000 per 1000 bricks.​

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

7

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
