Answer:
<A = 75degrees
Step-by-step explanation:
From the triangle given;
arcDA + arc AD + arcBD = 360 degrees
131 + 79 + arcBD = 360
210 + arcBD = 360
arcBD = 360 -210
arcBD = 150 degrees
Since the angle at the vertex <A is half that at the arc BD, hence;
<A = 1/2 arcBD
<A = 1/2 * 150
<A = 75degrees
Hence the measure of angle A s 75degrees

Answer:
$77.18
Step-by-step explanation:
A = total amount
P = principal
I = interest
A = P(1 + r/n)^n·t
A = 70(1+.05)²
A = 70(1.05)²
A = 77.175
I = A - P
