Studdy Solution
STEP 1
1. Triangle is a right-angled triangle with .
2. radians.
3. Side is opposite and has a length of .
4. We need to find the length of side , which is adjacent to .
STEP 2
1. Recall the trigonometric relationship for a right-angled triangle.
2. Use the tangent function to relate the sides.
3. Solve for side .
4. Round the answer to two decimal places.
STEP 3
Recall the trigonometric relationship for a right-angled triangle:
The tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side:
STEP 4
Use the tangent function to relate the sides:
For , the opposite side is , and the adjacent side is :
STEP 5
Solve for side :
Rearrange the equation to solve for :
Calculate and then find :
(using small angle approximation)
STEP 6
Round the answer to two decimal places:
Since , the answer is already to two decimal places:
The length of side is:
