Question

State true or false

$\tan {18}^0+\tan {27}^0+\tan {18}^0\cdot \tan {27}^0=1$

• A. True
• B. False

Answer 1

The correct option is B False

$tan180+tan270+tan180+tan270=1$

$0.32491969+0.50952544+0.32491969+0.50952544=1$

$1.66889026=1$

The left side $1.66889026$ not equal to rightside$1$.

Which means the given statement is false.
