Answer:
Side is 8 meters, Perimeter is 32 meters
Step-by-step explanation:
<em>One side </em>
Squares have 4 equal sides. Area is found using l*w, but the sides are all equal in squares. Therefore, the area can be found using:
a=s^2
We know the area is 64, so we can substitute that in
64=s^2
Take the square root of both sides

8=s
One side is 8 meters
<em>Perimeter</em>
Squares have 4 equal sides, and the perimeter is all the sides added up.
p=s+s+s+s
We know the side is 8, so we can substitute that in
p=8+8+8+8
p=4*8
p= 32
The perimeter is 32 meters
3/4 divide by 5 is equal to 3/20

<u>Trigonometric Ratios</u>
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

Calculating the inverse sine function:


Answer:
x = 0, y = -1
Step-by-step explanation:
10x = 5y + 5
y = 2x - 1
======================
10x = 5(2x - 1) + 5
10x = 10x - 5 + 5
x = 0
======================
y = 2x - 1
y = -1
