To Find :
The value of x and y from the figure .
Given Figure :
Given figure is a triangle , which is made up of two right triangles.
The smaller right triangle has x as its hieght
The bigger right triangle has y as its hypotenuse
Given :
- hypotenuse of smaller triangle = 12√2 cm
- Angle opposite to x in smaller triangle = 45°
- Angle opposite to x in bigger triangle = 30°
- hypotenuse of bigger triangle = y
We know that :
Solution :
In the smaller triangle,
hypotenuse = 12√2 cm
Side opposite to Theta = x
Theta = 45°
In the bigger triangle,
hypotenuse = y
side opposite to Theta = x = 12 cm
Theta = 30°
so, The values of x and y are :
- x = 12 cm
- y = 24 cm
hence, the correct option is a)

Additional information:
The valued of "sin theta" and "cosec theta" are just reciprocal of each other,
here, theta ≠ 0
The value of cosec theta is reciprocal just when , theta≠0
