Answer:

First answer.

Step-by-step explanation:

This is called the Arc length, here is the formula:

Arc length = (angle/360)*(2Pi*radius)

So,

(45/360)*(2*3.14*4)

= 3.14

SO Pi !!!!!

What is the value of x? Enter your answer in the box. x = A triangle with vertices labeled as A, B, and C. Side B C is the ba

Savatey [412]

Answer:

x = 5

Step-by-step explanation:

For better explanation of the solution, see the attached diagram of the problem :

The triangle angle bisector theorem states that the line which bisects an angle of a triangle divides the opposite two sides of the triangle in two equal segment which are proportional to the other two sides of the triangle.

Now, from the diagram : AD is the angle bisector angle B

$\implies\frac{AB}{AC}=\frac{BD}{CD}\\\\\implies \frac{9}{15} = \frac{(2x-1)}{(3x)}$

On Cross multiplication :

⇒ 9 × 3x = 15 × (2x - 1)

Using the distributive property,

⇒ 27x = 15×2x - 15×1

⇒ 27x = 30x - 15

Subtract 30x from each side:

⇒ 27x - 30x = 30x - 15 - 30x

⇒ -3x = -15

⇒ x = 5
