Determine the approximate value of x A. 18.85 B. 7.36 C. 8.69 D. 20.47
1 answer:
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

Given the graph of the function
and the graph of the function
when f(x) = g(x).
This occurs at the point(s) of intersection of the graphs of the function f(x) and g(x).
From the graph, we can approximate the points of intersection of the graphs of the function f(x) and g(x) to pe points (-1.9, 13.7) and (2.7, 0).
