Answer:
D) b =
Step-by-step explanation:
First, move all the terms that do not include b to the left side with S:
S = 2ab + 2bc + 2ac
S - 2ac = 2ab + 2bc
Now, factor out 2b from the right side:
S - 2ac = 2b(a + c)
Divide both sides by 2(a + c):
b =
Finally, multiply out the denominator:
b =
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos66° = =
( multiply both sides by x )
x × cos66° = 13 ( divide both sides by cos66° )
x = ≈ 32.0 ( to the nearest tenth )
