Fifteen years from now Ravi's age will be four times his present age.What is Ravi's present age ? Frame the equation and solve.

Archy [21]

Answer:

Ravi's age after 15 years = x+15

Ravi's age = 4 times his present age = 4x

According to question -

15 + x = 4x

=> 15 = 4x-x = 3x

=> 15 = 3x

=> x = 15/3

=> x = 5

Thus , Ravi's present age is 5 years.

Step-by-step explanation:

since they give us the side opposite of the given angle(Opposite) and we are trying to find for a (Adjacent/side), so we use TOA

tan(30)= $\frac{4}{a}$

i see u dont want it solved but ill solve it anyways

since a is on the bottom then lets switch them

$x=\frac{4}{tan30}$

x= 6.928
