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
