In a triangle, the three interior angles always add to 180°, so <span>the measure of the third angle = 180 - 57 - 74 = 49</span>°
Answer:
2940
Step-by-step explanation:
I used calculator
Hi there
First find the future value using the compound interest formula
The formula is
A=p (1+r/k)^kn
A future value?
P present value 1800
R interest rate 0.032
K compounded weekly 52
N time 10 years
A=1,800×(1+0.032÷52)^(52×10)
A=2,478.59
Now find the interest earned
I=A-p
A future value 2478.59
P present value 1800
So
I=2,478.59−1,800
I=678.59
It's b
Good luck!
Isn't it just 8^4? (sorry if i get this wrong, this is what i'm currently learning!!)
