Answer:
30°
Step-by-step explanation:
Area of a triangle can be found using either of the formula:
1. area = 1/2 x base x height
2. area = 1/2 ab sin c
Since we know the length of the two edges, we will use the 2nd formula:
Area = 1/2 ab sin c
Substituting the known values:
28 = 1/2 (14)(8) sin c
28 = 56 sin c
sin c = 0.5
c = 30°
Answer: X = 19
Step-by-step explanation: it is a three equation system, the problem is you don't have the third equation, so we have to infer it, and it's: PRQ + QRS = 180.
then we do as follows:
There are no horses in any of the stables. It says so at the beginning of the question

Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
