Question

astruct a AABC in which AB = AC = 6 cm, angleB = 70°, and angle
C = 70°. Measure angle A.​

Answer 1

Answer:

Given that a triangle in which AB=AC=6 cm and angle B = angle C=70 degree.

To measure the angle A :

Let ABC be the triangle.

Also given that AB=AC=6 cm and angle B=70 degree and angle C=70 degree

First construct a triangle ABC :

Draw a line segment AB of 6 cm and then draw another line segment AC of 6 cm from A.

Now join the the vertices B and C

Mark the measurements angle B=70 degree and angle C=70 degree

That is and

We know that the Sum of the interior angles in a triangle is

Therefore

Therefore the angle A is 40 degree
