$#4 Find the value of x. Round answer to nearest tenth.
shusha [124]

Answer:

Step-by-step explanation:

From the given right angle triangle,

The hypotenuse of the right angle triangle is x

With m∠54 as the reference angle,

The unknown is the adjacent side of the right angle triangle.

The opposite side of the right angle triangle is 19

To determine x, we would apply the Sine trigonometric ratio.

Sine θ = opposite side/hypotenuse. Therefore,

Sin 54 = 19/x

x = 19/Sin54 = 19/0.809

x = 23.5 to the nearest tenth.

The diameter of a circle of 255 π is:
melisa1 [442]

Hello from MrBillDoesMath!

Answer:   30


Discussion:

The area of a circle of radius R is given by the formula  

Pi * R^2

We are given that  the area is 225 Pi (Not 255 Pi as stated by the author)

Pi * R^2 = 225 * Pi

Divide both sides by Pi :

R^2 = 225  --->  R = 15

The diameter is twice the radius so the diameter = 30.

Add the sum and difference identities for sin x to derive 1/2 [sin(x+y)+sin(x-y)]=sin x cos y
Solnce55 [7]

Answer:

true

Step-by-step explanation:

1/2 (sin(x+y)+sin(x-y))

= 1/2 (sin x cos Y + cos x sin y + sin x cos y - cos x sin y)

= 1/2 * 2 sin x cos y

= sin x cos y

The expression is true.
