Answer:

m∠WXY+m∠ZXY=m∠WXZ

Step-by-step explanation:

You don't know the angles to be congruent (equal measures), complementary (measures add to 90 deg), or supplementary (measures add to 180 deg); all you know is that they are adjacent, so the sum of the measures of the two smaller angles equals the measure of the larger outer angle.

Answer: m∠WXY+m∠ZXY=m∠WXZ

An arithmetic sequence has a common difference of 2 and contains the value 86 at some point in the sequence. Which of the follow

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.
