Which equation represents the formula for the general term an, of an arithmetic sequence with a first term of 8 and a common dif

kykrilka [37]

The formula for the general term of an arithmetic sequence with first term, a, and a common difference, d, is given by
$A_n=a+(n-1)d$

Given that the first term of an arithmetic sequence is 8 and the common difference of 0.3, then the equation that represents the formula for the general term of the arithmetic sequence is given by
$A_n=8+(n-1)0.3=8+0.3n-0.3=7.7+3.3n$

Find the length of the angle inducated for each trapezoid.

Y_Kistochka [10]

First things first: all quadrilateral have an interior of 360⁰. With that info, you can do your exercice.

the first one:

the angle P =90⁰

the angle Q=90⁰

So you do the deduction:

360⁰-90⁰-90⁰-65⁰= 115⁰

the second one:

the angle F=60⁰

so you do the same thing as number one:

360⁰-60⁰-60⁰= 240⁰

240⁰/2= 120⁰

Voilà!
