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.
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.

It would be B because eaxh section either repeats itself or is close to repeating its previous part
Answer:
10
Step-by-step explanation:
because 7÷35 =5 but that would be for only one pencil so if u multiply that 5×2 it would be 10 pencils
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.
