In the triangle below, suppose that mZH=(x+9)°, mZ1=(4x-5)°, and m2 J= (3x)". Find the degree measure of each angle in the triangle.
(3x)
(4x - 5)
mZH = 0
m2i = 0
mLJ = 1
(x + 9)
. SERIOUS HELP NEEDED

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

you,

mrb

because 1.2 isnt half of 6 duh
