Measure of the angles are 50, 130, 50 & 130
Explanation:
As can be seen from the diagram, adjacent angles are supplementary and opposite angles are equal.
Let one angle be A
Other adjacent angle b will be 180-a
Given b = 2a + 30. Eqn (1)
As B = 180 - A,
Substituting value of b in Eqn (1) we get,
Measure of the four angles are
