Answer:
Step-by-step explanation:
step 1
Find the length side a
Applying the law of cosines
substitute the given values
step 2
Find the measure of angle B
Applying the law of sines
substitute the given values
step 3
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
Answer:
m∠c=42
Step-by-step explanation:
48×2=96
180-96=84
84÷2=42
We divide by 2 because c is an inscribed angle.

Answer:
- r = (n+1)/4
- the series diverges
Step-by-step explanation:
The ratio test asks you to look at the ratio of two successive terms of the sum. It is generally convenient to look at the ratio ...
where is the term shown in parentheses to the right of the summation symbol. Here, that ratio is ...
Most of the terms of the factorial product cancel, and the powers of 2 all cancel except for 2^2. So, the ratio of adjacent terms is ...
This gets larger and larger as n gets larger, so the series diverges.
