<h3>
Answer: 30.78181 meters</h3>
The value is approximate. Round that however you need to.
========================================================
Explanation:
- lowercase a = side opposite angle uppercase A
- lowercase b = side opposite angle uppercase B
- b = AC
Using the law of sines, we can say:
a/sin(A) = b/sin(B)
45/sin(30) = b/sin(20)
b/sin(20) = 45/sin(30)
b = sin(20)*45/sin(30)
b = 30.78181 approximately
You'll need to make sure your calculator is in degree mode.
Option C:
(11 + 8) + 1 = 11 + (8 + 1)
Solution:
Let us first define the associative property of addition.
<u>Associative property of addition:</u>
(a + b) + c = a + (b + c)
Option A: 5 + 3 = 3 + 5
This represents a commutative property of addition.
i.e. a + b = b + a.
So, it is not true.
Option B: 6 + 1 = 6 + 1
This is not under the property of associative.
It is not true.
Option C: (11 + 8) + 1 = 11 + (8 + 1)
(a + b) + c = a + (b + c)
This reflects the associative property of addition.
It is true.
Option B is the correct answer.
Hence (11 + 8) + 1 = 11 + (8 + 1) illustrates the associative property of addition.
Answer:
2.743 × 10^7
Step-by-step explanation:
The reason as to why 10 is to the 7th power is because the number that you turn into scientific notation (27430000), needs to be in ones form. Which is 7 decimal places away.
