Answer:
x = 6
Step-by-step explanation:
• ∠THX and ∠XHV have a common side HX and a common vertex H
This means they are two adjacent angles.
Then
m∠THX + m∠XHV = m∠THV
Then
53 + 12x−9 = 16x + 20
<u>Solving the equation</u>:
53 + 12x−9 = 16x + 20
⇔ (53 − 9) + 12x = 16x + 20
⇔ 44 = 16x - 12x+ 20
⇔ 44 - 20 = 4x
⇔ 24 = 4x
Answer:
The 30th term is 83
Step-by-step explanation:
we know that
An <u>arithmetic sequence </u>is a sequence of numbers such that the difference of any two successive members of the sequence is a constant called the common difference d
in this problem
so
The common difference d is 3
We can write an Arithmetic Sequence as a rule:
Find out the 30th term
we have
