Question 35

In a Rhombus ABCD, measure of angle CAB is 35°, what is the measure of angle ABC?

Solution

Given : $$\angle$$ CAB = 35°

To find : $$\angle$$ ABC

Solution : Diagonals of a rhombus bisect the angles of the rhombus

=> $$\angle$$ BAD = $$2 \times \angle$$ CAB

=> $$\angle$$ BAD = 70°

Sum of adjacent angles in a rhombus = 180°

=> $$\angle$$ BAD + $$\angle$$ ABC = 180°

=> $$\angle$$ ABC = 180° - 70° = 110°

=> Ans - (D)
