Answer:
The answer to your question is x = 8.69 cm
Step-by-step explanation:
From the image we can conclude that this is a right triangle, so we must use trigonometric functions to solve it.
Data
hypotenuse = x = ?
Adjacent side = 8 cm
Ф = 23°
Process
1.- We must use the trigonometric function cosine to solve this problem.
Cos Ф =
2.- Solve it for hypotenuse
hypotenuse x cos Ф = Adjacent side
hypotenuse = Adjacent side / cos Ф
3.- Substitution
hypotenuse = 8 / cos 23°
3.- Simplify and result
hypotenuse = 8 / 0.9205
hypotenuse = x = 8.69 cm

455 ÷ 50 = 9.1. The student tickets cost $9.10. (I think)
3x + 22 is the equation that represents the perimeter of the triangle. 4x + 10 is the perimeter of the rectangle. Setting the two equal:
and collecting like terms:
We find that the perimeter of both shapes is equal to 11 units.
