Math Problem Statement
determine the values of y.
Solution
To find the value of , let's solve the problem step by step based on the given triangle:
Given Data:
- The area of the triangle: .
- One angle: .
- The base of the triangle: .
- The height of the triangle (relative to the base): .
Formula for the Area of a Triangle:
The area of a triangle can be written as: where is the base and is the height.
We need to express in terms of and solve further.
Relation Between Base, Height, and Angle:
In a triangle, the height relative to base can also be calculated using trigonometry:
Substitute this into the area formula:
This simplifies to:
Solve for :
Rearranging for :
Using :
So:
Find :
Now that , substitute it back into:
