Question

if 15cot A = 8,then find the value of sinA and secA​

Answer 1

Step-by-step explanation:

15cot A= 8 then cotA= 8/15

cotA= adjacent side/opposite side.

by applying the formula (hyp)^2= side^2+ side^2

hyp= 17.

sinA= opposite side/hypotonuse

sinA=15/7

secA=hypotonuse/adjacent side

secA=8/15

Answer 2

15 cot A = 8

cot A = 8/15

cot A = base/perpendicular = 8/15

so, hypotenuse = √(8)²+(15)² = 17

Other Trigonometric values are :

sin A = perpendicular/hypotenuse = 15/17

cos A = base/perpendicular = 8/17

tan A = perpendicular/base = 15/8

cosec A = hypotenuse/perpendicular = 17/15

sec A = hypotenuse/base = 17/8
