Answer:



Step-by-step explanation:
step 1
Find the measure of side c
Applying the law of cosines

substitute the given values



step 2
Find the measure of angle A
Applying the law of sine

substitute the given values




step 3
Find the measure of angle B
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so

substitute the given values



4
let the number be x
so by the question , 2x+5=13
solving this we get ,
2x=13-5
2x=8
so x=4

Answer:
Just under 62 inches.
Step by Step:
4.9×2×Pi= 30.7876080052. x2= 61.5752160104
Answer:
The correct answer is option C. y = 31x + 154.
Step-by-step explanation:
Since x represents the days and she learns 31 words per day you would need to multiply 31 and the number of days (x).
This would look like 31x.
We also know she already knew 154 from the beginning which means we just have to add 154.
This leaves us with the equation y=31x + 154.
Hope this helps!
