The measure of each angle
First, we calculate the length of the three sides of the triangle.
This is calculated using distance formula
For AB
So:
For BC
For AC
So, we have:
By representation
So, we have:
By cosine laws, the angles are calculated using:
Collect like terms
Solve for
Take arc cos of both sides
Collect like terms
Solve for
Take arc cos of both sides
For the third angle, we use:
--- angles in a triangle
Make C the subject
The function relating in indira‘s height to the number of hours she mountain climbing is: y = -36.5x + 182.5
A linear equation is given by:
y = mx + b;
where m is the slope(rate of change), b is the initial value of y, y is the dependent variable and x is the independent variable.
Let x represent the number of hours spent climbing the mountain and y represent the distance above see level.
She starts at 182.5 meters above sea level, hence; b = 182.5 meters
She descends 36.5 meters each hour, hence m = -36.5 meter per hour
Therefore the equation becomes:
y = -36.5x + 182.5
