if sino=7/25 what are the other primary trig ratios.
solve this triangle.
y = 7, r = 25. Now we need x to find the other trig ratios. We use Pythagora's theorem:
Which quadrant is this? Take the sign that corresponds for the quadrant. Assume it's Quadrant I, thus
Now, now you solved the triangle. Simply substitute the values of x, y, and r in other ratios. I recommend that you find sine, cosine, and tangent, then take their reciprocals to get cosecant, secant, and cotangent. Remember:
