ScanSolve AI Answer
Step-by-step solution
3 stepsIdentify the knowns and unknowns in the right-angled triangle.
We are given:
- An angle .
- The side adjacent to the angle is .
- The side opposite the angle is .
- The hypotenuse (opposite the right angle) is .
Calculate the value of using the tangent function.
The tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side.
Substitute the given values:
We know that .
Multiply both sides by to solve for :
The value of is .
Calculate the value of using the cosine function.
The cosine of an angle in a right-angled triangle is the ratio of the length of the adjacent side to the length of the hypotenuse.
Substitute the given values:
We know that .
To solve for , cross-multiply:
The value of is .
