Question

Find he angles marked with letters

Answer 1

Angle d is marked congruent to 38°, so d=38°.
All angles in a triangle add up to 180°.
180°-38°=142°
The remaining angles are marked congruent to each other, so you divide 142/2.
142°/2=71°
The two other angles both equal 71°, so c=71°

Answer 2

The angle across from 38 degrees is 38 degrees.
