Answer:
The answer to your question is:
a) degrees = 60°
radians = π / 3
b) degrees = 135°
radians = 3/4 π
Step-by-step explanation:
a) csc Ф = hypotenuse / opposite leg
csc 60 = 2√3 / 3
180° ------------------ π rad
60° ------------------ x
x = 60π/180 = π/3
b) cot Ф = adjacent leg / opposite leg
cot 135° = - 1 / 1 = - 1 Draw the triangle of 45°
180° ----------------- π rad
135° ----------------- x
x = (135 π) / 180
x = 3/4 π
