3A. What is the value of BC. 3b) Find the measure of angle CAB to the nearest tenth
3.Explain briefly how you solved for side BC and angle CAB.

BC = 15

∠CAB =

Step-by-step explanation:

Pythagorean Theorem:

BC =

     = 15

:

∠CAB =

          = 61.92751306...° (round as needed)

is should be y = 5x

step-by-step explanation:

correct me if im wrong

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
