Answer:
36
Step-by-step explanation:
The tangents from the same point are equal. Each point of the triangle extend 2 tangents to the circle.
Tangents from the uppest point: 8+8=16
Tangents from the lowest point: 4+4=8
Tangents from the third point:
10-4=6
6+6=12
Perimeter: 16+8+12=36units

Answer:
See below
Step-by-step explanation:
Let P(x) be a predicate over the variable x. Rules from logic tell us that the negation of ∀xP(x) is ∃x(¬P(x)). That is, the negation operator ¬ satisfies ¬(∀xP(x))≡∃x(¬P(x)). Similarly, ¬(∃xP(x))≡∀x(¬P(x)).
Apply these rules to each statement to obtain:
a) ∃ a fish x, x does not have gills.
b) ∃ a computer c, c does not have a CPU.
c) ∀ movie m, m is not over 6 hours long. ⇔ ∀ movie m, m is under 6 hours long.
d) ∀ band b, b has not won at least 10 Grammy awards. ⇔ ∀ band b, b has won less than 9 Grammy awards.
Answer:
a=30 b=30 c= 75
Step-by-step explanation:
By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.
Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.
So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180
Subtract 30 from both sides and you are left with:
2c = 150
Divide by 2 on each side:
c= 75
18sqrt(15)
This has to be at least 20 characters long so yeaaaa
