The answer is going to be the second one, since if you plug them it, the equation is true
Answer: He is 18 years old right now.
Step-by-step explanation:
Let the present age of Ishaan be x
After 36 years,
his age will be x+36
According to question,
it is mentioned that Ishaan will be 3 times as old as he is right now ,
So, we will frame it in equation:

Hence, he is 18 years old right now.
Given that D is the mid point of CE ,
So D will bisect CE, it means the length of DE and CD is equal.
=> DE + CD = CE
As DE and CD are equal,
=> DE + DE = CE
=> 2 DE = CE
Putting values from the question,
=> 2( 7x - 1 ) = 10x + 18
=> 14x - 2 = 10x + 18
=> 14x - 10x = 18 + 2
=> 4x = 20
=> x = 20 / 4
=> x = 10 / 2
=> x = 5

Therefore, the value of x is 5
Answer:
19 days
Step-by-step explanation:
2 weeks = 14 days
14 + 5 = 19
Both sides aren't equal because 1-sin^2x = cos^2x and cos^2x / 1+cosx can never equal cosx
