It would be 2000 meters per second
Angle1 = 90 degrees
Angle2 = 15 degrees
Angle3 = 75 degrees (because 180-15-90=75 and all angles equal 180 degrees)
Side1 = 300
Side2 = x (unknown)
Solve for x:
X / sin(15degrees) = 300 / sin(75degrees)
X = (300•sin(15degrees)) / sin(75degrees)
X = 80.38...
= 80
Answer:
D
Step-by-step explanation:
A circle that contains all the vertices of a polygon - circumscribed
<h3>By Associative property of multiplication,</h3>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to use the associative property of multiplication
<em><u>Associative property of multiplication</u></em>
When we are multiplying two or three numbers, it does not matter where we put the parenthesis, it results in same answer

Therefore,

Thus associative property of multiplication is used to find solution
