Hello.
Since 3 < pi < 4,
√9 < pi √16
In fact, since pi^2 = 9.86,
<span>√9 < pi < √10.
Which means the you</span><span> can find pi between square roots √9 and √10.

Have a nice day
sin x= opposite / hypotenuse.
opposite=4
hypotenuse=5
sin x=4/5
x=arc sin (4/5)=53.13º
Answer: x=53.13º
Answer:
around 126
Step-by-step explanation:
Answer:
x=10.7
Step-by-step explanation:
Our proportion is
x/4=8/3
We can cross multiply to solve.
This is where you multiply one fraction's numerator with the other fraction's denominator and vice versa.
x*3=4*8
3x=32
Divide both sides by 3.
x=10.6666666667
Round.
x=10.7
(x + y)² and z² + 4(1/2 xy) both represent the area of the outer square and are equal.
Step-by-step explanation:
- Step 1: The below reasons explain why the expression is a true equation.
1. The expression (x + y)² finds the area of the outer square by squaring its side length.
[In the figure, side length of the outer square = x + y and area of a square = (side length)²]
2. The expression z² + 4(1/2 xy) finds the area of the outer square by adding the area of the inner square and the four triangles.
[In the figure the length of the inner square is z, the triangles have a base x and height y and area of a triangle = 1/2 base × height]
⇒ So the left hand side and right hand side of the expression is equal.
