so we have a 60-30-90 triangle (top one)
so since we know 6 is x (the side on the right angle and 60 degrees)
b is 2x or 2(6) = 12 
a is x√3 = 6√3 
for C I need to use a 45 45 90 triangle
Since b is 12 and its x√2  to find x we should write it as
x√2 = 12
√2     √2  divide by √2
x = 12/√2  but we must rationalize the denominator
12/√2  times √2/√2  = 12√2/2 and that's c
 
        
             
        
        
        
Answer:
<h2>1. subtract 3x, subtract 4, divide by -4</h2><h2 /><h2>2. add x</h2>
Step-by-step explanation:
1 + 3x = -x + 4.
subtract 3x 
1 = -4x + 4
subtract 4
-3 = -4x
divide by -4
(-3)/(-4) = (4x)/(-4)  ⇌ x = 3/4
-x + 6 = 5 - 3x
subtract 5
-x + 1 = - 3x
add x
1 = -2x

Given:
Point D is the centroid of Triangle ABC and DE = 9.
To find:
The measures of CD and CE.
Solution:
We know that, centroid is the intersection of medians and it divides each median in 2:1.
In triangle ABC, CE is a meaning and centroid D divided CE in 2:1. So,
Let the measures of CD and DE are 2x and x respectively.
DE = 9                (Given)

Now,



And,



Therefore, the measure of CD is 18 units and the measure of CE is 27 units.
