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
