Ok so you find squares
example
we know ataht √9=3 becuase 9=3*3 so √9=√(3 times 3)=√(3^2) =3
so we factor 230
230=2 times 5 times 23
we do not have any doubles so this is simplest form

Solve
Using sine rule, we have:

This gives:

So, we have:

In radical forms, we have:


Take LCM

Rewrite as:

Hence:

Answer:
m=-2n-13
Step-by-step explanation:
m+1=-2(n+6)
m+1=-2n-12
-1. -1
--------------------
m=-2n-13
Answer:
39.25 cm
Step-by-step explanation:
The formula for a circle is pi x radius x radius.
So to get the radius, you multiply 10 and 1/2. You should get 5. Then you multiply 5 by 5. You should get 25.
Then you multiply 3.14 and 25. You should get 78.5.
The last step is to divide 2 by 78.5. You should get 39.25
Answer:the measure of angle 6 is 60 degrees.
Step-by-step explanation:
The two horizontal lines ate straight and parallel lines. It is established that the sum of the angles on a straight line is 180 degrees. Looking at the given figure, angle 5 and angle 6 are on a straight line. Therefore
Angle 5 + angle 6 = 180 degrees. Therefore,If angle 5 is 120 degrees,then
Angle 6 + 120 = 180
Angle 6 = 180 - 120 = 60 degrees.
