2×1/2+1+3×1

1+1+3

5

Answer 2

Answer:

• 2sin 30° + cos 0° + 3sin 90° = 5

Step-by-step explanation:

Given:

• Trigonometric equation.

To Find:

• Value of - 2sin 30° + cos 0° + 3sin 90°.

Now, we all know that

$\implies{\tt{\sin 30^{\circ}=\dfrac{1}{2}}}$

$\implies{\tt{\cos 0^{\circ}=1}}$

$\implies{\tt{\sin 90^{\circ}=1}}$

Now, put the values in given equation.

$\implies{\tt{2\sin 30^{\circ}+\cos0^{\circ}+3\sin 90^{\circ}}}$

$\implies{\tt{2\times \dfrac{1}{2} +1+3\times 1}}$

$\implies{\tt{1 +1+3}}$

$\implies{\boxed{\tt{5}}}$
