Answer:
4/5
Step-by-step explanation:
cos B = 3/5
cos Ф = adjacent/hypothesis
hypothesis ² = adjacent² + opposite²
5²= 3²+ o²
25 = 9+o²
25-9=o²
16 = o²
√16 = o = 4
Sin B = opposite/hypothesis = 4/5
13=w-14/2
divide 14 by 2
13=w-7
add 7 to the other side (inverse)
20=w
OPTIONAL: switch the equation around
w=20
