71

Step-by-step explanation:

The given triangle is an isosceles triangle so the base angles are congruent (equal).  So, the angles are x + x + 38. Since the sum of the angles of a triangle equal 180°, we can set up an equation to solve for x:

x + x + 38 = 180

2x + 38 = 180

      -38   -38

2x         = 142

x          =  71

x = 90 , y = 43

Step-by-step explanation:

The large triangle is an isosceles triangle so the base angles are congruent (equal).  So, the angles are 47 + 47 + ∠A. Since the sum of the angles of a triangle equal 180°, we can set up an equation to solve for x:

47 + 47 + ∠A = 180

    94   +  ∠A = 180

               ∠A  = 86

Since ∠A is bisected by segment AD, then y = (86) = 43

ABD is a triangle with angles y , x, and 47.  Their sum equals 180°:

43 + x + 47 = 180

        x + 90 = 180

               x = 90
