Question

find the value of :-
5 tan 45 +3 sin 9o - 2 sin 30°​

Answer 1

$\huge \underline{ \underline{ \bf \purple{Solution :}}}$

$\large \sf \implies5 \tan45 \degree + 3 \sin90\degree - 2 \sin30\degree \\ \\\large \sf \implies 5 \times 1 + 3 \times 1 - 2 \times \frac{1}{2} \\ \\ \large \sf \implies 5 + 3 - 1 \\ \\ \large \sf \implies 7$

Answer 2

Answer:

hello

Step-by-step explanation:

tan 45°=1

Sin 90°=1

sin30°=1/2

5×1 + 3×1 - 2× 1/2

5+3 - 1

8-1 = 7
