Question

Plese solve the sum and give me fast

Answer 1

Explanation:

sin 0

4

5

means that in the right-angled

triangle, the opposite side is 4 and the hypotenuse is 5. the adjacent side must therefore be 3. (Pythagorean triple 3,4,5) However, as this is an angle in the 2nd quadrant,

the adjacent side is an x value and must be -3.

tan 0

opposite

adjacent

This leads to tan 0 4

or

- 3

3

This agrees with what we know from the CAST rule that Tan values are negative in the second quadrant.

Once you know the lengths of the sides of the

triangle, you can write down the value of any of

the trig ratio's for the angle 0

We have

adj = x = 3

opp = y = 4

hyp = r = 5

The signs will change depending on what quadrant the triangle is in.
