Answer:
52°, 90°
Explanation:
The two acute angles in a right triangle are complementary, because the third angle is 90°. For acute angles A and B, we must have ...
90° + A + B = 180°
A + B = 90° . . . . . subtract 90°; definition of complementary angles
B = 90° - A
For angle A = 38°, this tells us ...
B = 90° -38° = 52°
The other two angles in the triangle are 90° and 52°.
