Answer:
B. No
![Cos \ \theta\neq Cos (90-\theta)\textdegree](https://tex.z-dn.net/?f=Cos%20%5C%20%5Ctheta%5Cneq%20Cos%20%2890-%5Ctheta%29%5Ctextdegree)
Step-by-step explanation:
-A right angle triangle has two complimentary acute angles and one right angle.
-
is usually one of the acute angles and is equivalent to 90º minus it's complimentary acute angle.
-Complimentary angles add up to 90º.
#For complimentary angles:
![Sin \ \theta=Cos \ (90-\theta)\textdegree\\\\Cos \ \theta=Sin(90-\theta)\textdegree\\\\\therefore Cos \ \theta\neq Cos (90-\theta)\textdegree](https://tex.z-dn.net/?f=Sin%20%5C%20%5Ctheta%3DCos%20%5C%20%2890-%5Ctheta%29%5Ctextdegree%5C%5C%5C%5CCos%20%5C%20%5Ctheta%3DSin%2890-%5Ctheta%29%5Ctextdegree%5C%5C%5C%5C%5Ctherefore%20Cos%20%5C%20%5Ctheta%5Cneq%20Cos%20%2890-%5Ctheta%29%5Ctextdegree)
The two acute angles cannot have the same Cosine value.
Hence, she's not correct.
Answer:
<h2>4,520,389 = 4M + 5CM + 2DM + 3C + 8D + 9U</h2>
Step-by-step explanation:
In this proble, we defined:
- D represents tens.
- C represents hundreds.
- M represents millions.
- U is units.
So, the given number is 4,520,389, where we need to state the proper variable according to the position of each digit and its value.
4,520,389 = 4M + 5CM + 2DM + 3C + 8D + 9U
In words, the first term represents 4 millions, the second term represents 5 hundred thousands, the third term represents twenty thousands, the fourth term represents three hundreds, the fifth term represents eighty and the las term represents 9 units.
