Answers

Answer:

Culture has a significant impact on heroes. For starters, it influences how a person or character perceives a particular situation or idea, as well as their point of view on a variety of ideas and topics. Next, it has an impact on how the hero is portrayed in the story. Third, it influences how a character reacts to an idea or situation.

Culture has an impact on heroes. We see an example of this in 'Black Ships Before Troy,' where in Achilles' culture, to be a hero, you must be brave and fight. This is also evident in 'Heart of a Samurai,' where Manjiro's culture dictates that in order to be a hero, you must provide for your family.

The value of x from the given congruent triangles is 23 units.

In the figure ΔABC and ΔDEF are given.

What is the congruence theorem?

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Consider, ΔABC and ΔDEF, we have

AB=DE (Given)

∠BAC=∠EDF (Given)

AC=DF (Given)

So, ΔABC ≅ ΔDEF

We know that, by CPCT

BC=FE

⇒ x-4=19

⇒ x=23 units

Therefore, the value of x from the given congruent triangles is 23 units.

Answer:

x=9

Step-by-step explanation:

Original equation: 16x-8-14x=10

Combine like terms: 2x-8=10

Add 8 to both sides: 2x=18

Divide by 2 on both sides: x=9

Let me know if this helps!

Answer:

x=9

Step-by-step explanation:

16x-8-14x=10

16x+-8+-14x=10

(16x+-14x)+(-8)=10 ( Combine like terms)

2x-8=10

Add 8 to both sides

2x-8=10

+8 +8

2x=18

Divide both sides by 2

2x=18/2

x=9
