Answer:

  • CD = 6.3

Step-by-step explanation:

The triangles CED and CGF are similar since two sides are on same line and one side is parallel.

<u>Corresponding sides have equal ratios:</u>

  • CG/CE = CF/CD
  • CG/CE = (CD - 1.8)/CD
  • 6/(6 + 2.4) = (CD - 1.8)/CD
  • 6/8.4 = (CD - 1.8)/CD
  • 1/1.4 = (CD - 1.8)/CD
  • 1*CD = 1.4CD - 1.4*1.8
  • 0.4CD = 2.52
  • CD = 2.52/0.4
  • CD = 6.3

By what property are x+3(7-x) and x+21-3x equivalent
Lorico [155]

Answer:

The given expressions x+3(7-x) and x+21-3x  are equivalent by using the distributive property

Step-by-step explanation:

Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent

To find for what property the given two expressions are equivalent :

x+3(7-x)=x+3(7)+3(-x)

=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )

Therefore the given expressions x+3(7-x) and x+21-3x  are equivalent by using the distributive property

What is the measure of ∠x
scZoUnD [109]

Answer:

∠x = 63°

Step-by-step explanation:

The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:

128 + x = 180

x = 52

∠BAC = 52°

The angles in a triangle all add up to 180°, so we can set up another equation to find x:

52 + 65 + x = 180

117 + x = 180

∠x = 63°
