The solution of cos θ = −0.3 is θ = 107.45760312 degrees
<em><u>Solution:</u></em>
Given that we have to find the primary solution of 
To solve this equation, you must find the unknown (theta)
Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta
We know that arccos (-0.3) = 107.45760312 degrees
[ If you reference a unit circle or use a calculator ]
Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees
Answer:
y = x
Step-by-step explanation:
Since the quantities form a proportional relationship then the equation relating them is
y = kx ← k is the constant of proportion
The constant k is found using any ordered pair from the graph
Using (4, 4 ) , then
4 = 4k ( divide both sides by 4 )
1 = k
y = x ← equation of proportion
We can’t see the question

Step-by-step explanation:
i am so sorry but i have now idea
The average can be found by adding them all up and dividing that number by the number of items. If the result have you a number that's more than the largest or less than the lowest, you did it wrong.
(75+70+90+60+50+90+70)/7
= 505/7
=72.14
