Answer:
Step-by-step explanation:
Given f(x)=
We have to find
In order to find we have to make x as the subject of the formula
Let us assume f(x)=y
⇒
Subtracting both sides by 5
Dividing both sides by 2
⇒
Now substituting y with x
we have
Now
=
So option (ii) is correct
Answer:
Step-by-step explanation:
In isosceles trapezoid JKLM,
Given: and
Since, JKLM is an isosceles trapezoid so each pair of base angles is congruent.
As, we know that the sum of the angle of a trapezoid is
The angles are:
Therefore,
Combine like terms;
Subtract 40 from both sides we get;
Simplify:
Divide both sides by 56 we get;
To find the angle of :
Simplify:
Therefore, the value of angle of
