Step-by-step explanation:

Use SOH-CAH-TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Side a is adjacent to the 29° angle, and 14 is opposite of the 29° angle. So use tangent:

tan 29° = 14 / a

a = 14 / tan 29°

a ≈ 25.3

Side c is the hypotenuse, and 14 is opposite of the 29° angle. So use sine:

sin 29° = 14 / c

c = 14 / sin 29°

c ≈ 28.9

How would you convert #11?

The prefix 'd' stands for "deci-", which is a multiplier of 1/10. This 1 dL is 1/10 of a liter. Hence

1 L = 10 dL

Multiply this equation by 6.88, and you get

6.88 L = 68.8 dL
