Answer:
Infinite triangles
Step-by-step explanation:
A triangle can have angles which total to 180 degrees
When one triangle ABC is constructed with degrees 80, 80 and 40 respectively, then similar triangles can be formed by transforming ABC with a real scale factor say k
k can take any real values positive, negative, rational, irrational etc.
Hence we can say given a triangle ABC with given angles there can be an infinite number of triangles with the same angles which will be similarl to ABC and carry an equal proportion with corrresponding sides.

Answer:
177.3 feet
This is a classic find the vertex of a parabola question.
if this was a calculus class the solution would be to take the derivative and set it equal to zero... -32t+ 105 = 0
BUT i assume that you are not in a calculus class..
so we try plan "B" the highest (or lowest) point of parabola is it's vertex
the vertex formula is [-b/2a,f(-b/2a)]
in your problem a = -16, b=105, c= 5
so the "X" (TIME) is located at -(105)/(2*-16) = 3.28
plug in 3.28 into -16(3.28)^2 + 105(3.28) + 5 = 177.27
and you will get

Answer:
2) k=17/45 and 4) 29/22
Step-by-step explanation:
You can look for friendly numbers such as
48 and 2, split 82 in 80 and 2 and then associate the numbers conveniently
48+ (2+80)=
(48+2)+80=
50+80 which you can do it and is 130 or
50+80=
50+50+30=
100+30 which is 130
