Find the measure of each angle indicated

D) 45 degrees

Step-by-step explanation:

145 = 100 + x

Subtract 100 from both sides

45 = x

OR

180 - 145 = 35

<FEG = 35

100 + 35 + x = 180

135 + x = 180

Subtract 135 from both sides

x = 45

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
