`In `DeltaABC` , ltB=90^(@),tan A=( 3)/(4)`and length of BC =180 m, ten find the length of hypotenuse of `DeltaABC`.

Explanation

To find the length of the hypotenuse of triangle ABC, where angle B is 90 degrees, tan A = 3/4, and the length of BC is 180 m, we can follow these steps:

### Step 1: Understand the triangle and the given information
In triangle ABC:
- Angle B = 90 degrees
- BC = 180 m (this is the side opposite to angle A)
- tan A = 3/4
