two years ago, kim ean invested RMx in her account which earn y% simple interest. after 1.5 years, she noticed that the amount had become RM 10450 and today the amount is RM 10600

try soting them out first

step-by-step explanation:

1. supplementary angles

2. acd and bcd

step-by-step explanation:

the answer, i believe is y-8=1(x+4)

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
