Which of the following statements are true? (Check all that apply.) ∠1 = 35°

∠3 and ∠4 are vertical angles.

∠2 is a right angle.

∠1 and ∠4 form a straight angle.

∠4 = 145°

1 and 4 form a straight angle

Step-by-step explanation:

just this one, all other options make no sense

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

8121 because

130,000 divided by 16 is 8121
