Answer:

∠B = 52°

Step-by-step explanation:

Since we know that the sum of all inner angles of the triangle equal to 180°, then we can make the following equation,

5x + 3x + 2x + 20 = 180

10x = 180 - 20

10x = 160

x = 160 / 10

x = 16

Since we know that ∠B = (2x + 20)°, we can calculate the following

∠B = (2x + 20)°

∠B = (2(16) + 20)°

∠B = (32 + 20)°

∠B = 52°

Determine whether the sequence converges or diverges. If it converges, give the limit. 60, 10, five divided by three, five divid

vodomira [7]

$A_n = 60, 10, \frac{5}{3}, \frac{5}{18}$

Using geometric sequence form, we can rewrite it as:
$A_n = a_1 \cdot r^{n-1}$
$A_n = 60 \cdot \frac{1}{6}^{n - 1}$

Since r < 1, there exists a limit, and thus, it is said to converge.
$\lim_{n \to \infty} 60 \cdot (\frac{1}{6})^{n - 1}$
$= 0$

Since the ratio is still positive, as n tends towards infinity, the graph of the sequence will never go below the horizontal. Thus, we say that the limit of the function is zero, which means that as we increase the size of n, eventually after the infinite-th time, it will hit zero.
