Cos^2 + cos^2 tan^2 (break the brackets)
Cos^2+ cos^2 • sin^2/cos^2 (divide out the cos^2)
Cos^2+ sin^2 (Cos2+ sin^2= 1)
= 1
Answer:
<h2>C</h2>
Step-by-step explanation:
using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get
8^2+23^2=c^2
then, using our big math brains, we get 64+529=c^2
adding together the numbers, we end up with 593
just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C
17.156 is the rational number, if the number can be put into fraction form then it is considered rational
