Question

In ABC, AB=AC and the measure of

Answer 1

The triangle ABC is shown below.

Since, ABC is an isocelles triangle, the angles opposite to the sides are equal. Therefore, angle B equal to angle C is 76.

Thus, the measure of angle A is,

`\begin{gathered} \measuredangle A=180-(76+76) \\ =28 \end{gathered}`

Therefore, the measure of angle A is 28 degree.
