Question

what is cot square theta - 8 cot theta + 15

Answer 1

Answer:

cosec theta = 17 / 15

sec theta =  17 / 8

Step-by-step explanation:

We know that,        

cot theta = Base/perpendicular

cosec theta = Hypotenuse/Perpendicular

sec theta = Hypotenuse/base

a |\

   |   \

b   ------ c

Let, abc is a triangle.

here,

cot theta = bc/ab

cosec theta = ac/ab

sec theta = ac/bc

cot theta = 8/15 means bc = 8 and ab = 15  

and we also know that

Base² + perpendicular² = Hypotenuse²

so, ac² = ab² + bc²

    ac² = 15² + 8²

    ac² = 225 + 64 = 289

    ac = √289 = 17

cosec theta = 17 / 15

sec theta =  17 / 8
