What is the measure of ∠A, the exterior angle of the triangle shown below?

88

Step-by-step explanation:

Each triangle has a sum of 180 degrees. So we find the missing angle with this rule.

180-38-50.

The angle is 92 degrees.

Now to find the angle of A, each angle adds up to 180 on a line. so 180-92. So you get 88

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
