6. Write down the values of the six
trigonometric functions of the angle A:
( sin A, cos A , etc.)
5
A
8
7. Suppose that tan A =
2
5
(a) Draw a right triangle showing the angle A
and side lengths 2 and 5 in the correct positions.
(b) Use the Pythagoras theorem to find the
length of the last side of the triangle.
(It’s OK to leave this as a square root)
(c) Find the values of cos A and sin A.
