Answer:
A complete angle is one which measures 360∘360∘.
The three angles
6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘
add up to 360∘360∘, as per the question.
6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘
⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘
⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘
⟹2x+3y+z=90∘⟹2x+3y+z=90∘
This is the required relation.
Question 11:
Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false
Question 12:
A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection
Hence this statement is true
Question 13:
The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true

❖ A number y increased by 5 is at least -21.
❖ First, if you come across the word "increased" it means we
"increase" a number, or add something to that number, like
y increased by 5 
Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.
So we have
<em>Solving for y</em>
<em></em>
- Subtract 5 on both sides:-
So the values of y greater than or equal to -26 will make this inequality true.
<h3>Good luck with your studies.</h3>
