Answer:
11.3 Km
Step-by-step explanation:
Consider the right triangle formed by AB and West.
The acute angle WAB = 270° - 250° = 20°
and West is the adjacent side of the right triangle with AB the hypotenuse
Using the cosine ratio in the right triangle, then
cos20° = 
= 
Multiply both sides by 12
12 × cos20° = adjacent
11.2763.. = adjacent, that is
B is 11.3 Km west of A
Answer:
C
Step-by-step explanation:
Total of 40 cups and 25 of them are chocolate so the proportion for chocolate would be 25/40
Answer:
x=81.25, A=65, B=94, C=21
Step-by-step explanation:
corresponding angles of similar triangles are equal, hence angle measurements of A, B, and C. To solve for x, set up a ratio (60/48=x/65) and solve
Answer:
<h2>
3</h2>
Step-by-step explanation:
Any polynomial can only have as many zeros as is the highest exponent at x.
A cubic polynomial it's: ax³+bx²+cx+d. The highest exponent at x is 3 so it is the largest number of its zeros.
