The Answer Is 7.5
Tangent and 8 makes a right triangle, which is great because you could find the diameter and divide it by 2 to find the radius.
64+d^2=289
d^2=225
d=15
15/2=7.5

Answer:
Step-by-step explanation:
m = 500 - 10d
16 n^2 -10n + 129 = 8n^2 -8
We collect the terms:
8n^2 -10n + 137 = 0
The steps for completing the square:
1) Move the "non X" (or "non N") term to the right:
8n^2 -10n = -137
<span>2)<span> Divide the equation by the coefficient of N² which in this case is 8
n^2 -1.2n = </span></span><span><span>-17.125
</span>
3) Take the coefficient of "N"; divide it by 2; square it; add it to both sides of the equation.
-1.2 / 2 = -.6
-.6^2 = .36
</span>
n^2 -1.2n +.36 = <span>-17.125
+.36
Take the square root of both sides:</span>
(n-.6)*(n-.6) = sq root(

<span>
-16.765
</span>
</span>
</span>
)
That's about as far as I can go.
Answer:
28.57
Step-by-step explanation:
3.14×0.5=1.750
50÷1.75=5000÷175 to eliminate the decimal points
5000÷175=28.571
then we round the answer to the nearest tenths
=28.57
