​

Answer 1

Answer:

Step-by-step explanation:

2sin30⁰+cos0⁰+3sin90⁰

=2×(1/2)+1+3×1

=5 (ans)

Answer 2

Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\sf\pink{2sin30° + cos0° + 3sin90°} \\ \sf\pink{ = > 2 \times \frac{1}{2} + 1 + 3 \times 1 } \\ \sf\pink{ = > 1 + 1 + 3} \\ \sf\pink{ = > 5} \\ \sf\purple{sin0 =0 \: \: cos0° = 1 \: tan0° = 0 } \\ \sf\purple{sin30° \: = \frac{1}{2 \: } cos30° = \frac{ \sqrt{3} }{2} \: tan = \frac{1}{ \sqrt{3} } } \\ \sf\purple{ sin45° = \frac{1}{ \sqrt{2} } \: cos45° = \frac{1}{ \sqrt{2} } \: tan45° = 1} \\ \sf\purple{sin60° = \frac{ \sqrt{3} }{2} \: cos60° = \frac{1}{2} \: tan60° = \sqrt{3} } \\ \sf\purple{sin90° = 1 \: cos0° = 0 \: tan0° = \infty }$
