In parallelogram abcd, ac is diagonal, the measure < abc is 40°, and the measure of < acd is 57°. what is the measure of < cad?

Option D

Step-by-step explanation:

In this question we use properties of parallelogram and angle sum property of a triangle.

In parallelogram ABCD

As, we know that opposite angles of parallelogram are equal

Therefore,

Now, in triangle ADC

We know that sum of all the angles of a triangle is

Subtracting 97 from both sides we get

Measure of
