Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
The measure of angle 1 is 75°. Hope you get it.
B I did this to:) it’s pretty easy once u get the hang of it
Answer:
$24.35
Step-by-step explanation:
We will use the compound interest formula provided to solve this problem:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 1% into a decimal:
1% ->
-> 0.01
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:


Lastly, subtract <em>A </em>from the principal to get the interest earned:
