Answer:
60°
please look into the solution down here.
Step-by-step explanation:
since BD bisects it, then the angles should be bisected symmetrically, or in other words, ANGLE ABD = angle DBC,
hence,
4x = 2x +30
2x = 30
x = 15
therefore, angle DBC = 2x + 30 = 2(15) + 30 = 60°.
Answer:

Step-by-step explanation:
The formula for this equation is

a is the final result
p is the starting amount (deposited)
r is the interest rate
n is the number of times it's compounded
t is the time
because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117
Please double check me I may be wrong, this is my second time doing these type of questions
