Question
Find the measure of the missing angle x of the triangle.

- 28o
- 45o
- 36o
- 27o
Hint:
We know the angles opposite to equal sides are equal.
angle EBD and angle ABC are vertically opposite angles.
The correct answer is: 36o
Given that AC=BC;
We know the angles opposite to equal sides are equal.
So, angle BAC = angle ABC
angle EBD and angle ABC are vertically opposite angles.
A pair of vertically opposite angles are equal in measure.
So, angle EBD = angle ABC
angle x = 36.
So, the measure of angle x is 36.
