Divide 20 by 4=5
then 5 by 7=5/7
k=5/7
Answer:
60in²
Step-by-step explanation:
Since lateral surface area means all the shapes except the base, we will ignore the square in the middle.
A=1/2(b*h)
A=1/2(10*3)
A=15in²
Now we will multiply the area by 4 or the number of other shapes besides the base.
60in²

We want to convert this equation in terms of m, where 
While solving this problem, I instantly noticed the
in the first term of the equation. Replace that with m.

Simplifying the rest is not as obvious. Using the distributive property, we can change
to ![[7(x^2+3)]](https://tex.z-dn.net/?f=%5B7%28x%5E2%2B3%29%5D)
Do you see the "m" in here? Look again if you don't.
Now we can simplify the equation to
and this cannot be simplified further.
I'm always happy to help someone who appreciates the help! :D
The answer is the first option,

Start by knowing that the cosine function is

.
For angle θ, find the adjacent side and hypothesis of the given triangle. These are 24 and 26, respectively. Simply put those into the cosine function, simplify, and you have your answer.
