Question

In a question in boards we had to find the value of tan in which base was missing. H was 3 and P was 1.5
I applied pythagoras theorem to get B as 2.6
The actual answer was 1/root3 but i have written 15/26 which is similar. Will marks be deducted

Answer 1

Step-by-step explanation:

लम्ब = 1.5 , कर्ण = 3

आधार = √(कर्ण)² - (लम्ब)²

= √(3)² - (3/2)²

= √9 -9/4 = √(27/4) = (3/2)*√3

= 3/2 * 1.732 = 5.196/2 = 2.598 (~2.6)

tan = लम्ब/आधार = (3/2)/(3√3/2)

= 3/3√3 = 1/√3 = 15/15√3

= 15/15*1.732 = 15/25.98 = 15/26
