Question

2sin30°+cos0°+3sin90​

Answer 1

Step-by-step explanation:

We Know ThaT :

Sin90° = 1

Cos0° = 1

Sin30° = 1/2

= (2×1/2) + 1+ 3

= 1+1+ 3 = 4

= 4

Answer 2

${\underline{\boxed{ \purple{ \: {\textsf{\textbf{\purple{ We have learned trigonometric ratios :- }}}}}}}}$

$→\underline\mathtt\blue{GIVEN:}$

$→ 2sin30° + cos0° + 3sin90°$

$\underline\mathtt\blue{Put \: the \: values \: :}$

$→ 2sin30° + cos0° + 3sin90° \\ \\ </p><p>→ 2( \frac{1}{2} ) + 1 + 3 \times 1 \\ \\ = 2 \times \frac{1}{2} + 1 + 3 \\ \\ = \frac{2}{2} + 4 \: \\ \\ = \sf\cancel\dfrac{2}{2} + 4 \\ \\ = 1 + 4 \\ \\ = \huge\mathcal{\fcolorbox{lime}{b}{\blue{5}}}$
