Complete question
To find
, Beau found
and
. He said that since 5 is between 4 and 9,
, is between 2 and 3. Beau thinks a good estimate for
, is
Is his estimate high or low? How do you know?
Answer:
The estimation is high because 5 is very close to 4 so
will also be very close to
which is lower than the estimate
In order to get a good estimate
The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them
i.e
![2.1^2 = 4.41](https://tex.z-dn.net/?f=2.1%5E2%20%3D%20%204.41)
![2.2^2 = 4.84](https://tex.z-dn.net/?f=2.2%5E2%20%3D%20%204.84)
![2.3^2 = 5.29](https://tex.z-dn.net/?f=2.3%5E2%20%3D%20%205.29)
From here we can see that
lies between 2.2 and 2.3 but is closer to 2.2
So a good estimate for
is 2.2

Answer:
The angles are 45°, 60° , 75°
Step-by-step explanation:
<h3>
Angle sum property:</h3>
Sum of all the angles of a triangle is 180°.
Equation:
3x + 5x + 4x = 180
Combine like terms,
12x = 180
x = 180/12
![\sf \boxed{x = 15}](https://tex.z-dn.net/?f=%5Csf%20%5Cboxed%7Bx%20%3D%2015%7D)
3x = 3 *15 = 45°
5x = 5* 15 = 75°
4x = 4 *15 = 60°
Try adding a picture next time maybe...?
3(2y-3)=27
6y-9=27
6y=36
y=6
