2. ΔABC is isosceles
Step-by-step explanation:
Given : m∠A = 50
m∠BCD = 180 - (m∠BDC + m∠DBC)
= 180 - (100 + 30)
= 50
then
m∠A = m∠BCD
therefore ΔABC is isosceles
we are given
investment amount is 2300
so,



it is compounded monthly
so,
n=12
now, we can use formula

now, we can plug values
t=7/12
and we get

now, we can find FV
