Step-by-step explanation:

→ 2 sin 30 + 2 Tan 45 - 3 cos 60 - 2 cos² 30

→ 2(1/2) + 2(1) - 3(1/2) - 2(√3/2)²

→ 1 + 2 - 3/2 - 3/2

→ 1 + 2 - 3

→ 3 - 3

→ 0

2 sin 30°+3 cos 60°-3 tan 45°​

Special Angles Value:

sin30° = 1/2 = 0.5

cos60° = 1/2 = 0.5

tan45° = 1

substitute values into the equation:

2 sin 30° + 3 cos 60°- 3 tan 45°​

2(0.5) + 3(0.5) - 3(1)

1 + 1.5 - 3

2.5 - 3

-0.5

or if answer needs to be in fraction, revert it back as: 0.5 = 1/2

- 1/2

So answer is -1/2  or  -0.5
