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°.
