Answer»

cot A = 8/15; (hypo)^2=( opp)^2 +(adj)^2 = (15)^2 + ( 8)^2 = 225 + 64 =289, ( hypo)=17; sinA=(15/17); cosA= (8/17); secA= ( 17/18)

15 cotA= 8cotA= 8/15cosec^2A= 1+cot^2A = 1+64/225... = 225+64/225= 289/225cosecA= √289/225= +-17/15sinA= 15/17

Sin A=15/17Sec A=17/8

correct answer issinA = 15/17SecA = 17/8
