A carpenter needs to cut a small triangular pice of wood for part of a jewelry box. He knows the dimension shown and that 0=68°. What is the length of a to the nearest tenth of a centimeter?

Answer:
36.0 cm
Step-by-step explanation:
use cosine to find the value of a
cos(68) = a/96 Multiply both sides by 96
a = cos (68) * 96
a = 35.96
Round to nearest tenth: 36.0 cm
