The answer is 100.

<u>Step-by-step explanation</u>:

<u>Given</u>:

A circle is centered on the point(-1,5) and contains the point(7,11)

<u>To find</u>:

Area of a circle.

<u>Formula</u>:

(x – a)2 + (y – b)2 = r2

<u>Solution</u>:

D(A,B)=√ (xa − xb)2 + (ya − yb)2

D(A,B)=√ (7 + 1 )2 + (11− 5)2

D(A,B)=√ (8 )2 + (6)2

D(A,B)=√ 100

D(A,B)=10

Substituting in the above equation

(x + 1 )2 + (y – 5)2 = 100

the vertices of ABC are points A(1,1), B(4,1), and C(4,5). find the cosines of the angles of the triangle.
pickupchik [31]

Answer:

  • cos(A) = 3/5
  • cos(B) = 0
  • cos(C) = 4/5

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the cosine of an angle and the sides of the triangle.

  Cos = Adjacent/Hypotenuse

__

<h3>Angle A</h3>

In the given triangle, the hypotenuse is AC. The side adjacent to angle A is AB, so its cosine is ...

  cos(A) = AB/AC

  cos(A) = 3/5

__

<h3>Angle B</h3>

The right angle in the triangle is angle B. The cosine of a right angle is 0.

  cos(B) = 0

__

<h3>Angle C</h3>

The side adjacent to angle C is CB, so its cosine is ...

  cos(C) = CB/AC

  cos(C) = 4/5
