For this item, we represent first the proportionality constant by the variable k. Being directly proportional to both b and c, these variable will be in numerator and d will be in the denominator. That is,
                                  a = kbc / d
Substituting the known values,
                                 400 = k(16)(5) / (2) 
The value of k is 10. The equation that models the relationship is therefore,
                                   a = 10bc/d

Which triangles are congruent by SAS?
boyakko [2]

Answer:

Option A

Triangles ABC and TUV

Step-by-step explanation:

Given three triangles ABC , FGH and TUV

For triangles ABC and FGH, given that

DF =AB

DH = AC

and angle F = angle A

This cannot be taken as SAS congruence because the angle F is not included between the equal sides.  Two triangles can be congruent by SAS only if two sides and included angle are congruent.

For triangles ABC and TUV we have AB=TU, AC = TV and

included angles between these sides are equal.

So these two triangles are congruent

We write corresponding sides only in order Hence ABC = TUV

and Not VTU =ABC

So option A is true.

4 and 8 are corresponding angles.  Corresponding angles are on the same side of parallel lines cut by a transversal

What fraction is equal to 50% of 1/4
Kipish [7]
1/8


50% is the same as 1/2, so you just multiply 1/2 by 1/4 to get the answer. First, multiply the numerators. 1*1 is 1. Then, multiply the denominators. 2*4 is 8. So, your answer is 1/8. If you want to check this, multiply 1/8 by 2 and you will get 1/4.

Geometry ( WILL GIVE BRAINY)
Step2247 [10]

Answer:

1:

we have a rule that is (n-2)×180

while n = number of sides

2:

exterior angle of a polygon = 360 ÷ number of sides

so 360÷25=14.4

3:

octagon is 8 side, so as we said: (8-2)×180 = 1080

4:

lets make an equation, we know that (n-2)×180 = the sum

so (x-2)×180=720

180x -360 = 720

180x = 1080

x=6
