Answer 2

Answer:

3 is the value of  2tan45° + cos30° - sin60° + sin90°.​

Step-by-step explanation:

2tan45° + cos30° - sin60° + sin90°​

Know that,

tan45° = 1

cos30° = √3/2

sin60° = √3/2

sin90° = 1

Substituting,

2(1) + √3/2 - √3/2 + 1

2 + √3/2 - √3/2 + 1

2 + 1

3

∴ 3 is the value of 2tan45° + cos30° - sin60° + sin90°​.
