A circle is inscribed in a 40º-60º-80º triangle. The points of

Vladimir [108]

Answer:

A = 50°

B = 60°

C = 70°

Step-by-step explanation:

If we draw a line from each vertex through the center of the circle, we perpendicularly bisect the line joining the adjacent tangent points.

We then know the original angle is halved and the remaining angle of each right triangle is complementary to half the original.

Now we can subtract the known angles along each line of the original side to find the remaining angle

What is the sum of the first 12 terms of the geometric series below 1/2+2+8+32+

Georgia [21]

∴ $\frac{1}{2} +2+8+32.......12^{th}term$ =2796202.5

Step-by-step explanation:

First term(a) = $\frac{1}{2}$ common ratio(r) = $\frac{2}{\frac{1}{2} }$ =4

n= 12

$S_{n}=\frac{a(r^n-1)}{(r-1)}$

$S_{12}=\frac{\frac{1}{2}(4^{12}-1) }{4-1}$ =2796202.5

∴ $\frac{1}{2} +2+8+32.......12^{th}term$ =2796202.5
