Answer:
21
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
Replace t with -2 and solve for a number. It should work since it's not a fraction.
Answer:
<h3>80° has a tangent of 5.6922..</h3>
Step-by-step explanation:
We are given value of tangent trigonometric ratio = 5.6922.
We need to find the angle in degrees whose measure has a tangent of 5.6922..
So, we need to find the value of
.
On plugging
in calculator, we get
80.03°.
Now, we need to round it to the nearest whole degree.
Therefore, 80.03°≈ 80°.
<h3>Therefore, 80° has a tangent of 5.6922..</h3>
To solve this I will use substitution method.
First we need to find x so
X - 4 = 9
X -4 (+4) = 9 (+4)
X = 13
Now we can substitute 13 where there is an x in the second equation so instead of
2x - 3y = 11 it would be
2(13) -3y = 11
Now
26 - 3y = 11
26 (-26) -3y = 11 (-26)
-3y = - 15
Y= 5
To prove our answer we can do 2(13) - 3(5) = 11 which is 26 - 15 = 11
X = 13
Y = 5
