Question

What is the measure of 2A, in degrees? A. 60° B. 120° C. 150 D. Cannot be determined

Answer 1

Answer:  120 degrees  (choice B)

=========================================================

Explanation:

Triangle ABC is isosceles because sides AB and AC are the same length (both 8 units long).

The angles opposite these congruent sides are known as the base angles, and they are congruent angles.

So the base angles B and C are 30 degrees each.

----------

Next, we'll use the idea that for any triangle, the three angles always add to 180

So,

A+B+C = 180

A+30+30 = 180

A+60 = 180

A = 180-60

A = 120 degrees

Answer 2

Look they have told about the area we have to find about what is the area of A so we have to find a area so it means that we have to find the area of Of the two points which I have been like us one is 30° so the another which is on the behalf at the upper side it means means as it is bad let means it has the same value as that one to me is 30 multiply 30 means it is multiplied by two times so it would be 60°
