Answer:
CU = 12
Step-by-step explanation:
Clearly from the diagram of the triangle we can say that,
AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.
Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.
Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .
Thus CU will be 
times of CF (median) .
Given is Cf equals 18 ,
Thus , CU = ×18 = 12.
So, CU equals 12 .

Answer:
1) triangles are similar
Step-by-step explanation:
The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.
The height ratios are ...
∆WXY/∆UVW = 4/6
The width ratios are ...
∆WXY/∆UVW = 4/6
The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.
_____
Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.

Answer:
0.8 OR 
Step-by-step explanation:
The reciprocal of any number is the number that it multiplies by to equal 1.
The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.
E.g.
No. X/Y * Y/X (its reciprocal) = 1
So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.
1.25 = 125/100
Now we just flip 5/4 to get our reciprocal:
= 0.8
Test: 0.8 * 1.25 = 1
The reciprocal of 1.25 (
) is 0.8 ().
Hope this helped!
