Question

Cos alpha is minus 12/13cot beta is 24/7 90less than180 and 180 less than 270 thenthe quadrant in which alpha beta lie

Answer 1

Answer:

α & β lies in 3rd Quadrant

Step-by-step explanation:

Cos alpha is minus 12/13cot beta is 24/7 90less than180 and 180 less than 270 thenthe quadrant in which alpha beta lie

Cos alpha is minus 12/13

Cosα = -12/13

=> α Lies in 2nd Or 3rd Quadrant

Cotβ = 24/7

=> β lies in 1st  or 3rd Quadrant

=> β lies in 3rd Quadrant

if α & β are in same quadrant

=> α & β lies in 3rd Quadrant

Answer 2

Answer:

yes they lies in 3rd quadrant
