Question

15 cot A=8 find sin a and sec a?​

Answer 1

Step-by-step explanation:

•cotA=8/2

•cotA=adj/opp

•applying Pythagoras theorem

•AC=17

•sinA=opp/hyp

•. =15/17

•secA=hyp/adj

•. =17/8

Answer 2

Answer:

sinA = 15/17 , secA = 17/8

Step-by-step explanation:

cotA= 8/15             equation 1

we know 1 + (cotA)^2= (cosecA)^2

(225 + 64)/225 = (cosecA)^2

root(289/225) = (cosecA)

15/17 = sinA

from 1

cosA = 8/17 therefore secA = 17/8
