Pablo generates the function f (x) = three-halves (five-halves) superscript x minus 1 to determine the xth number in a sequence.
which is an equivalent representation?
f(x + 1) = five-halvesf(x)
f(x) = five-halvesf(x + 1)
f(x + 1) = three-halvesf(x)
f(x) = three-halvesf(x + 1)

Here's one way:
using your protractor first draw a horizontal  line segment 

from the left end of the line segment construct another line segment that is 50° and moves above the original line segment.  from the other end of the line segment construct another line segment that is 95° and moves above the original line segment.   if you drew both line segments long enough, they should intersect.   that intersect must be the 35° angle
part 2 - the triangle is an obtuse, scalene triangle.   it is obtuse because it has an angle larger than 90°   (95°).   it is scalene because when 3 angles of a triangle are different degrees, the side are different as well.
