Answer:
1a. 0.5291
1b. 2.0370
1c. 4.2661
2a. 25.7693
2b. 1.8665
2c. 24.0420
2d. 5
Step-by-step explanation:
sin(34) = 0.5290826861 ≈ 0.5291
12 tan(63) = 2.036997025 ≈ 2.0370
5 cos(56) = 4.2661005386 ≈ 4.2661
2a. You have to use tan because tan is opposite over adjacent.
You have 
You have to use inverse tangent.

2b. You have to use cos because cos is adjacent over hypotenuse.
You have 
0.2666429324 = 
x = 1.8665005268 ≈ 1.8665
2c. You have to use sin because sin is opposite over hypotenuse.


2d. Use the pythagorean theorem.
