The vertical angles are congruent (have the same measures).
Therefore you have the equation:
∠E = ∠F → 9x + 12 = 3x + 24 |-12
9x = 3x + 12 |-3x
6x = 12 |:6
x = 2
Answer:
15050
Step-by-step explanation:
Hello!
So basically, this arithmetic sequence follows the rule (3n-1). What you are looking for is the summation of (3n-1) with a lower limit of 1 and an upper limit of 100. This, plugging it into a calculator (etc. symbolab) or even calculating it manually, we get ∑↑100↓n=1⇒3n-1=15050.
