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
1: 3/4 2: 6/8 I’m pretty sure is the answer sorry if I’m wrong
Answer:
d
Step-by-step explanation:
don't know how to explain it, not even sure of the answer, but just wait someone will help u out,believe me u will find.
Step-by-step explanation:
the products is the 2 parts of the segment lines are the same.
so,
5×8 = 4x
is correct (the second option).
which means
40 = 4x
x = 10

Step-by-step explanation:
When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.
KL·KM = KJ·KC
Assuming the marks inside the circle apply only to the lengths inside the circle:
8(8+x+5) = 7(7+2x+1)
104 +8x = 56 +14x
48 = 6x
8 = x
Then the measure of MK is ...
MK = x+13 = 8+13
MK = 21
