In the figure at right, it is given than bdc is straight, bd = da, and ab = ac = dc. find the size of angle c

Step-by-step explanation:

We are given that BDC is straight.

BD=DA

AB=AC=DC

Let

Then,

Because AB=AC, angle made by two equal sides are equal.

Let

In triangle ABC

sum of angles of triangle

Exterior angle is equal to sum of two interior angles on the opposite side.

Substitute the values then we get

Hence, the size of angle C=

anser is a

step-by-step explanation:

negitive slope
