Angle A = 133 degrees
47 degrees and angle A are supplementary angles/a linear pair, which means that they add up to 180.
180 - 47 = 133
Angle B = 15 degrees
The sum of the interior angles in a triangle is 180.
a + 32 + b = 180
133 + 32 + b = 180
b = 15
Angle D = 58 degrees
32 degrees and angle D are complementary angles, which means that they add up to 90.
90 - 32 = 58
Angle C = 75 degrees
The sum of the interior angles in a triangle is 180.
c + d + 47 = 180
c + 58 + 47 = 180
c = 75
Hope this helps!! :)
