If angle BÂD=19°Find angle ACB​

Mathematics
1 answer:

Answer:

<ACB = 19°

Step-by-step explanation:

<BAD is a peripheral angle, meaning the angle it intersects is twice it. This means that arc AB is 2*19 or 38. Now, <ACB is an inscribed angle because it has a vertex on the circle. An inscribed angle is half the angle it intercepts. This means <ACB is 1/2 arc AB or 19.

Answer:

Step-by-step explanation:

Factoring an expression is the process of undoing the multiplication.

Assume you have a function f(x):

f(x)=x^2+2x-48

This can be factored:

f(x)=(x+8)(x-6)

Using multiplication and the distributive property, you arrive back to:

f(x)=x^2+2x-48

Then you can see clearly that all we've done is reverse the multiplication.

Which ideas from the excerpt would be most appropriate to
Elenna [48]

Answer:

Step-by-step explanation:

A) Popular novels from the past often ask provocative questions that are important to consider today.

In this speech, President Reagan uses the ending of a popular novel of the '60s to help pose his question about whether history still has a place for America, her people and her ideals. He takes provocative questions written in an old novel and uses them to show important subjects that need to be addressed today.

B) Many Americans have given up and say that the nation is no longer great or a land of dreams.

In his speech Reagan states that many Americans have lost their faith in their country and no longer believe that it is a place for dreams and greatness. This people say that Americans must "cut our expectations, conserve and withdraw"

C) President Reagan believed that John Wayne would argue that he was not the last American hero, because there are many more.

After the passing of the iconic Hollywood actor, John "Duke" Wayne, the headlines on the newspapers called him the "Last American Hero". Reagan, being a close friend of the late actor, stated that Wayne would've hated being called that, since he knew there were still many other heroes in America.
