(b) In the figure alongside, AB I BC and a - b= 10° then find the values of a and b.

Step-by-step explanation:

a - b = 10^

Let a and b be X

x + x = 10

2x = 10

x = 5

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

they can both be solutions depends on the equation
