Question

If tan theta=8/15 find the values of t-ratios of theta

Answer 1

Answer:

tan theta = 8 / 15

=> cot theta = 1 / tan theta

= 15 / 8

=> cosec theta = √ 1 + cot² theta

= √ 1 + (15/8)²

= √ 1 + 225/64

= √289/64

= 17/8

=> sin theta = 1/cosec theta

= 8/17

=> cos theta = √1 - sin²theta

= √1 - (8/17)²

= √1 - 64/289

= √225/289

= 15/17

=> sec theta = 1 / cos theta

= 17/15
