Find the cosine of 38 degrees and then find its reciprocal.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 38 degree angle is equal to 180 - 38 = 142 degrees.
The measure of angle b would depend on the sum of the angles a and b which has not been given so therefore a solution is not possible.
Angles do not have lengths. They are measured in terms of rotation about the vertex.

An acute angle
90 - 38 = 52 degrees.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 38 degree angle is equal to 180 - 38 = 142 degrees.
The measurement could be the value, 38 degrees, or it could be the actual act of measuring the angle.
Acute , to start with, then right, obtuse, straight and reflex.
x+y=180 y= x+38 x+(x+38)= 180 2x+38=180 -38 =-38 2x = 142 x= 71 plug it in equation 71+71+38= 180 angle 1 = 71 angle 2 = 109
I found it! It's 52 degrees.
The Complement of 52 degrees would be 38 degrees, because 90 degrees minus 52 degrees is 38 degrees. Hope That helps!
All up a triangle has 180 degrees on the interior so if we add 45 and 38 together we get 83. 180 minus 83 equals 97. So the degrees of the last angle is 97 degrees. You learn this is seventh grade math.
38 is an acute angle and 105 is an obtuse angle
If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
