Question

If tan 3x = 1 and cot 6y = 0( x,y are acute angles), then the value of x+y is :
a) 45
b) 30
c) 90
d) 6

Answer 1

Answer:

30

Step-by-step explanation:

tan 3x = 1                cot 6y = 0

3x = 45                          6y = 90

x = 15                               y = 15

x+y = 15+15 = 30
