What is the measure of A?

So measure of angle A is 50degrees

Step-by-step explanation:

As we know that A+B+C=180(supplementary angles)

A+100+30=180

A+130=180

A=180-130

A=50degrees

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

it has changed from the width and the height.
