Check the picture below.

bear in mind that, a perpendicular line stemming from the right-angle like so, creates three similar triangles, a large one, containing the other two smaller ones, a medium and a small.

so.. .we can just use the medium and small proportions.

solve for "x".

Please really need the correct answer for this or I'll fail algebra 3

Answer:

$4\pi$

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation $x*\frac{\pi }{180}$ , x = 72

S = $72*\frac{\pi }{180} * R$

given that R = 10

S = $\frac{72*10*\pi }{180}$

S = $\frac{720*\pi }{180}$

We simplify 720 as 180 goes into 720 4 times and we get

S = $4\pi$

Hope this helps

Find the 16th term for the sequence a(n)=7-2n.

N76 [4]

In the expression that you are given, n is the is number in the sequence. So in this scenario, n=16. So substitute the 16 into the equation. $a(n)=7-2(16)=7-32=-25$ . So the 16th term in the sequence is -25.
