Answer:
-8/5 is the answer
Answer: b=-8/5
Step-by-step explanation:
Additive inverse,
5
8
Multiplicative inverse,
−
Explanation:
For a number
a
, it's multiplicative inverse
b
is such that
⋅
=
1
which is the multiplicative identity.
, it's additive inverse
c
would be such that
+
0
where
is additive identity.
Thus, for
It's additive inverse be
.
Then
Now, adding
to both sides,
Let the multiplicative inverse be
⇒
Multiplying both sides with
(in degrees)
x = 15.09478709
sin(x) = 25/96
55°
Using cosine law
67² = 74² + 14² - 2(74)(14)cos(L)
cos(L) = 169/396
L =55.18378419
Answer: I think it is
