Big ifs, question writers. These are of course approximations.
The "co" in cosine comes from complementary angles. It means since


Answer: cos 48° = 2/3
Similarly,


Answer: tan 69.5° = 8/3
Answer:
Step-by-step explanation
You must find the common denominator for all of them.
A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.
B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.
C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.
D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
Answer:
4 I guess
Step-by-step explanation:
Because
3-1=2
2^2=2*2=4
The answer is 36 because in order to find area you multiply length and width so:
A= L x W
9 x 4 = 36
