Z POY = 90° anda : b= 2:3, find c.

Answer 1

Answer:

When x is inversely proportional to y it can be written as x is directly proportional to 1/y

I.e. X ∝ 1/y

Mathematically it can be expressed as

X=k/y

Where k is some constant value

Substitute the given values of x and y in the above equation

9=k/15

=>k =9*15

=>k=135

In second statement it is given as y=30 and we need to find the value of x

Substitute the same in above equtaion

X*y=k

X*30=135

X=135/30

=> x=4.5
