Lengths in Right Triangles

         

In the above right angled triangle, if θ=20\theta=20^\circ and the length of the side adjacent to θ\theta is 98,98, what is the length of the side opposite to θ\theta?

In the above right angled triangle, if θ=20\theta=20^\circ and the length of the side adjacent to θ\theta is 21,21, what is the length of the hypotenuse?

In the above right angled triangle, if θ=30\theta=30^\circ and the length of the side opposite angle θ\theta is 9999 cm, what is the length of the adjacent side (A) in cm?

Given a triangle with one angle of 90,90^\circ, the triangle is called a right angled triangle and the side opposite the right angle is called the hypotenuse. The side opposite the angle θ\theta in the above diagram is called the opposite side and the remaining side is called the adjacent side. If θ=20\theta=20^\circ and the length of the hypotenuse is 8181 cm, what is the length of the opposite side in cm?

Note: The above diagram is not drawn to scale.

In the above right angled triangle, if θ=20\theta=20^\circ and the length of the side opposite to θ\theta is 80,80, what is the length of the side adjacent to θ\theta?
