Answer:

B = 44°

c = 27.8

b = 19.3

Step-by-step explanation:

m∡B = 180 - (90 + 46)

sin46° = 20/c

c = 20 / sin 46°

c = 27.8

b² + 20² = 27.8²

b² + 400 = 772.84

b² = 372.84

b = $\sqrt{372.84}$

b = 19.3

shusha [124]

Answer:

B. $a_{n} = a_{n-1}+2$ ; $a_{1} = 2$

Step-by-step explanation:

According to the statement, we find that the following two conditions must be observed:

$a_{i} = 86$ (Eq. 1)

$a_{i}-a_{i-1} = 2$ (Eq. 2)

Since the difference between two even numbers leads to another even number. Hence, $a_{1}$ must be an even number and the correct answer is B.
