I believe that (1,-5) is the only correct solution.
Answer:
x ≈ 2.3 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos55° =
=
( multiply both sides by 4 )
4 × cos55° = x , thus
x ≈ 2.3 cm ( to 1 dec. place )
Angle side angle would be it
Answer:
the equation of g(x) is,
Step-by-step explanation:
The transformation of the function is defined as:

where, b represents the horizontal shift.
if b> 0 then, the function f(x) shifts b units left and if b< 0 ; then the function shifts b units right
As per the statement:
The function f(x)=2x−5 is a linear function.
It is given that:
g(x) represent f(x) after a horizontal translation 3 units to the right.
⇒
then

⇒
⇒
Therefore, the equation of g(x) is, 
You first have to find the length of each side.
AB=4
BC=4
CD=4
AD=4
Since this is a quadrilateral, two sides will have the same length, in this case, they all do so you can pick any two sides.
4(4)=16.
