Given:
The point on the terminal side of theta is (4,-7).
To find:
The exact values of sin theta, secant theta, and tangent theta.
Solution:
If a point is on the terminal side of theta and , then
The point on the terminal side of theta is (4,-7). Here, and .
Now,
Therefore, .
A straight line is 180º . This means that
3x+6x=180.
3(20)+6(20)=180
X=20
