Answer: 3
Step-by-step explanation:
Multiply by
Divide by to isolate
Since we have the same base (2), we equal their exponents.
Around 4980 to 5010 could be the exact number
Answer:
<em>x=74.73°</em>
Step-by-step explanation:
<u>Law of cosines</u>
In a general triangle, the law of cosines relates the lengths of the sides of the triangle to the cosine of one of its angles.
The law of cosine is expressed as:
Where a and b are the lengths of two sides of the triangle, x is the angle contained between them, and c is the other side length.
If all side lengths are known, we can solve the above equation for the angle x:
From the image, we must select a and b as the sides adjacent to angle x in any order. Thus a=17, b=22, c=24. Substituting:
Operating:
Using a scientific calculator:
x=74.73°
Answer:
--- You
--- Another student
Reason: Because there is a variation in the given dimensions
Step-by-step explanation:
Given
Your measurement
Another students'
Solving (a): The area
Area is calculated as:
For you
For the other student
Solving (b): Reason for the variation in the areas
The given measurements are estimates of the dimensions of the rectangle.
Since there is a variation in the estimates, there will be some level of variation in the calculated area.
