Answer:

Using CPCTC, we know that congruent parts of the congruent triangles are congruent.

Given: ∆ABC ≅ ∆DEF

BC ≅ FE  ⇒ CPCTC. IF FE = 5 (Given), & FE ≅ BC (CPCTC) ∴ BC = 5 (Transitive Property of Equality.)

BA ≅ DE ⇒ CPCTC. IF DE = 11 (Given) & DE ≅ BA (CPCTC) ∴ BA = 11 (Transitive Property of Equality.)

m∠D ≅ m∠A ⇒ CPCTC. Congruent Parts of Congruent Triangles are Congruent. If ∆ABC ≅ ∆DEF (given), then through CPCTC, m∠D ≅ m∠A.

Answer:

BC = 5

BA11

angle D = 27

Step-by-step explanation:

If the triangles are similar

ABC ≅ DEF

That means AB ≅ DE

BC ≅ EF

and CA ≅ FD

We want to find AB  so it is equal to DE  

BC = EF = 5

BA = AB = DE =11

We also know  the angles are equal

A = D

B = E

C = F

Angle A = angle D = 27

13. A number half of that number end one-third of that number are added. The result IS 22. What 15 the number
nordsb [41]
X=is the number looked for.
x/2=is the half of "x".
x/3=is the one-third of the "x".
We suggest this equation:

x+(x/2)+(x/3)=22
Least common multiple=6
6x+3x+2x=132
11x=132
x=132/11=12

Te number is 12

To check:
A number (12)+ half of that number (6)+ the one-htird of that number(4) is:22

12+6+4=22

I need help in "Matlab' with how to "Create a column vector from 15 to -25 with a step size of 5"
Alekssandra [29.7K]

Answer:

x=[15:-5:-25]'

Step-by-step explanation:

In order to create a vector you need to use this command:

x = [j:i:k]'

This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector
