Question

किमती काढा: 5sin 30° + 3tan 45°

Answer 1

Solution :

5sin 30° + 3tan45°

= 5 × (1/2 ) + 3 × 1

= 5/2 + 3/1

= 2.5 + 3

= 5.5

Or

= 11/2

Answer 2

$\bf\purple{QuestioN:-}$

किमती काढा:

5sin 30° + 3tan 45°

$\bf\pink{AnsweR:-}$

5sin 30° + 3tan 45°

As we  know that,  

 

$\red\longrightarrow\bf{Sin\:30\°=\dfrac{1}{2}}$

$\red\longrightarrow\bf{Tan\:45\°=1}$

Then,

$\implies$ 5 sin 30° + 3 tan 45°

$\implies$ 5 × ½ + 3 × 1

$\implies\bf{\dfrac{5}{2}+3}$

$\implies\bf{\dfrac{5}{2}+\dfrac{6}{2}}$

$\implies\bf{\dfrac{11}{2}}$

Therefore ;

5sin 30° + 3tan 45° = 11/2
