Answer:
missing 9400
Step-by-step explanation:
14300+16700+17900+18500=67400
67400<76800
76800-16700=9400
Ashely reads 3 chapters in her book each night. Jordon reads 8 chapters in a book each night. Will reads 2 chapters per night, but they are very long. How many chapters do they read per night all together?
The figure is a scalene triangle, and the exact length of side a is √13
<h3>How to determine the exact length of side a?</h3>
To calculate the length of a, we make use of the following law of cosine
a² = b² + c² - 2bc * cos(A)
Using the values in the figure, we have:
a² = 3√2² + 5² - 2 * 3√2 * 5 * cos(45)
Evaluate the expression
a² = 18 + 25 - 30
Evaluate the sum and the difference
a² = 13
Take the square root of both sides
a = √13
Hence, the exact length of side a is √13
