Answer:

a = 22.85 in.

c = 27.9 in.

B=35°

Step-by-step explanation:

Use tangent to find a and use the given angle and 16 in.

tan(55)=a/16

a = 22.85 in.

Use cosine to find c and use the given angle and 16 in.

tan(55)=16/c

c = 27.9 in.

To find angle B, have the sum of the three angles add up to 180.

55+90+B=180

145+B=180

B=35°
