Pls help me answer this question

Step-by-step explanation:

This is an isosceles triangle because side AC and side AB are congruent (they are both marked with single slash marks). That means that angle B and angle C are also congruent. Angle B also measures 2x. To find the measure of each angle we will use the Triangle Angle-Sum Theorem:

x + 2x + 2x = 180 and

5x = 180 so

x = 36

Angle A = 36, B = 72 and C = 72

x = 36 degrees

Step-by-step explanation:

This is an isosceles triangle, because two legs are equal.  The angles opposite these legs are therefore also equal:  <B = <C = 2x.    The sum of the interior angles must be 180 degrees.  Therefore,

x + 2x + 2x = 180 degrees, and 5x = 180 degrees.  Thus, x = 36 degrees.
