Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)
Answer: The answer is 80%.
Step-by-step explanation: Let us define the following events.
B = the event that the shirt is blue,
G = the event that the shirt is green
and
S = the event that the shirt is striped.
So, n(B) = 8, n(G) = 7, n(B and S) = 5, n(G and S) = 4.
n(S) = 5 + 4 = 9.
We have

Therefore, the required probability is

Thus, the answer is 80%.
Answer:
Hey mate !!
Your answer is so simple :)
<h2>V= 9°</h2>
Go through the explanation to understand.
Step-by-step explanation:
In the given question,
We see that 105° and it's adjacent angle (i.e. 8v+3° ) forms a supplementary angle. Which means the sum of 8v+3°+105° is 180°
<h3>Therefore,</h3>
According to the question






Answer the value of v is 9° .
Hope it helps you!!

90 = k*15
constant of proportionality = 80 / 15 = 6 Answer
