Answer:

Step-by-step explanation:

We have the sequence: 50, 54, 58, ....

The sum to n terms is a + (n - 1)d....where a is the first term and d is the difference between terms. Hence, a = 50 and d = 4

so, f(n) = 50 + 4(n - 1) => 4n + 46

Hence, in row 20 we have 4(20) + 46 => 126 seats

Answer:

$\large\boxed{x\approx56.44}$

$\large\text{It's close to 55.0}$

Step-by-step explanation:

$\tan12^o\approx0.2126\\\\\tan12^o=\dfrac{12}{x}\to\dfrac{12}{x}=0.2126\qquad\text{convert the decimal to the fraction}\\\\\dfrac{12}{x}=\dfrac{2126}{10000}\qquad\text{cross multiply}\\\\2126x=120000\qquad\text{divide both sides by 2126}\\\\x=\dfrac{120000}{2126}\\\\x\approx56.44$
