Question

find the value of x if 36,90,90,x are in proportion

Answer 1

Answer:

x = 225

Step-by-step explanation:

Product of middles = 90 x 90

Product of extremes = 36 x (x)

90 x 90 = 8100

8100/ 36 = 225

Rechecking :-

90 x 90 = 8100

36 x 225 = 8100

36 x 225 = 90 x 90

Hence, 225 is the correct answer

Answer 2

Given - Values

Find - Value of x

Solution - The value of x is 225

Ratio and proportion form -

$\frac{36}{90} = \frac{90}{x}$

Performing multiplication and division

$x = \frac{90 \times 90}{36}$

$x = \frac{8100}{36}$

x = 225

So, the value of x is 225
