Alright remember, if any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
k+1=0
k-5=0
Set the first factor equal to 0 and solve
k=-1
Set the next factor equal to 0 and solve
k=5
The final solution is all the values that make (k+1)(k-5)=0 true.
k=-1, 5
Hope this helped you out :)

Step-by-step explanation:
Solving for given the equation, :
Solving for when
Answer: The triangle is a obtuse triangle. Because two angles are less than 90 and 110 is a obtuse angle.
Hope it helps
The angle of elevation from point C to point A is
<em><u>Solution:</u></em>
Given that we have to find the angle of elevation from point C to Point A
Given in figure that, angle A =
Given is a right angled triangle ABC where angle B =
We have to find angle C
The angle sum property of a triangle states that the angles of a triangle always add up to 180°
Therefore, in given triangle ABC
angle A + angle B + angle C = 180
Therefore angle C =
