Answer:
30°
Step-by-step explanation:
53°+97°+x = 180°
The sum of three angles must equal 180°
Solve the equation.
150°+x = 180°
x = 180°-150°
x = 30°
Therefore, x = 30°

I think it's option B ...
Answer:
95.03in.^2
Step-by-step explanation:
Use the formula, A= pi r^2 and D=2r
A=1/4pi d^2=1/4 times pi time 11 squared
If you multiple 13 18=234 then subtract that by 13 18 203 that would be the area so 13 is less than 18
Answer:
x = ± √(-15n-7) / √2n (± (-15n-7)^(1/2) / (2n)^(1/2))
Step-by-step explanation:
Factoring?
2nx² + 15n+7 = 0
2nx² + 0*x + (15n+7) = 0 ... ax²+bx+c=0
Roots: x = (-2b ± √b²-4ac)) / 2a = (0 ± √0-4*2n*(15n+7)) / 4n
x = ± (√8n (-15n-7)) / 4n = ± (2√2n(-15n-7)) / 4n = ± (√2n(-15n-7)) / 2n
or x = ± √(-15n-7) / √2n
