120, because 12 times 10 is 120.
Answer:
Half of cord 24/2 = 12
Step-by-step explanation:
In the circle with r = 13 we have 13^2 = 12^2 + a^2 where a = the distance from the centre of this circle to the cord. Thus a = 5. Then the distance from the cord to the other circle centre is 21 - 5 = 16. In the second circle you can write r2^2 = 16^2 + 12^2. The r2 = sqrt (400) = 20
Answer:
50
Step-by-step explanation:
The triangle is an isosceles triangle as shown with the lines on the sides of the triangles. That means the unknown angle is 35 degrees since angle Q cannot be 35 degrees. Solve the equation:
2x + 80 = 180
2x = 100
x = 50

Remark
The idea here is to take any two successive terms and divide one by the other. which is the divisor and which the dividend will be discussed below.
Step One
Set up the ratio for the common ratio between terms that come one after another.
Mathematically this is written as
r =
So just to see how this looks
t_(n + 1) = 3
t_n = 9
r =
r = 1/3
Does this work for other examples? Let's try a more complicated looking one.
t_(n) = 1/9
t_(n+1) = 1/27
r = t_(n + 1) / t_n
r =
r =
r = 1/3
