Answer:
<h2>25m²</h2>
Step-by-step explanation:
If you want to find the area, you have to use this formula:
Formula:
LxW
L: length
W: Width
Here we have a square, and the sides are all 5 meters long, that means that we have to just do 5x5 to get the answer.
5x5=?
Hope ya remember the 5 table, lol, I know everyone does
5x5=25
so hence, your answer is 25m²
Thanks!

Step-by-step explanation:
I know you have 1 and 3 right but I'm sorry about not knowing the rest.
Answer:
see bottom
Step-by-step explanation:
divide through by 4
x2 - 2x - 3 = 0
x2 - 3x + x - 3 = 0
(x2 - 3x) + (x - 3) = 0
x(x - 3) + 1(x - 3) = 0
(x + 1) (x - 3) = 0
x + 1 = 0 and x - 3 = 0
x = -1 and x = 3
Answer: cos(Θ) = (√15) / 4
Explanation:
The question states:
1) sin(Θ) = 1/4
2) 0 < Θ < π / 2
3) find cos(Θ)
This is how you solve it.
1) Use the fundamental identity (in this part I use α instead of Θ, just for facility of wirting the symbols, but they mean the same for the case).

2) From which you can find:

3) Replace sin(α) with 1/4
=>

=>

4) Given that the angle is in the first quadrant, you know that cosine is positive and the final answer is:
cos(Θ) =

.
And that is the answer.
