Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
Answer:
Yes it is absolutely right.
we have

the vertex of the function g(x) is the point 
the vertex of the function f(x) is the point 
so
the rule of the translation of g(x) to f(x) is
(x,y)------> (x,y-4)
that means
the translation is
units down
therefore
the equation of the function f(x) is

therefore
<u>the answer is</u>
