Complementary = angle+other angle = 90 degrees
90-26(given)=64
There is only one complimentary angle to any other angle, so 64 is the only other one. Sin(64)=.899
Sin(64)=cos(26)
This is because cosine and sine are actually THE SAME. Cosine exists because there's sine. Cosine is sine moved over on a graph a bit. The sine of any angle, plus 90degrees (or pi/2) is equal to the cosine of that angle
Cos(x)=sin(x+90) <--degrees
Cos(x)=sin(x+pi/2) <-- radians(from unit circle)
Unit circle has 90 degrees at pi/2 which is why that works. Using a graphing calculator in degrees, you'd use the first equation I gave to prove that they're equal, and in radian mode, you'd use the second one. Cosine is Co in front of sine. Co meaning complimentary, which is why the problem equals each other when solved
Answer:
49
Step-by-step explanation:
There is no answer choices so I can't really select an answer so I just provided my own. If you do provide the answer choices and my answer is wrong tell me and I will gladly change it. Anyways my explanation is since there are 7 days in a week and she collected 7 leaves for a week you would find this answer out by multiplying 7 by 7. 7x7=49
Answer:
0
Step-by-step explanation:
16 (x +2) - 8 =16x +24
16x +32 - 8 = 16x +24
16x +24 = 16x + 24
16x - 16x = 24 - 24 ( put like terms together)
0 = 0
