Trig Ratio Worksheet

Master trig ratios! Practice sine, cosine, and tangent to find missing sides on right triangles.

In the second column, state what trig ratio you used to solve the problem (type sine, cosine, or tangent). In the third column, find the missing side of the right triangle. Round to the nearest tenth. IF IT'S A WHOLE NUMBER JUST LEAVE THAT WITHOUT THE DECIMAL. Problem sine, cosine, or tangent Missing side answer sine 3.8 tangent 7.5 cosine 15.5 cosine 19.1 sine 14.7 cosine 5.3 cosine 35.1 tangent 27.7 tangent 9.1 sine 14.7 tangent 3.2 sine 11.2 cosine 4.6 sine 17 tangent 32.2 sine 11.1 tangent 13.9 tangent 17.6 tangent 26.2 tangent 29.7 sine 23.1 cosine 10.6 cosine 5.5 cosine 16.3 sine 28.9 Find x. Round to the nearest tenth IF NEEDED otherwise just leave it as a whole number. 13.8 8.1 6 5.5 4.6 12.9 6.2 2 Type "Y" for yes and "N" for no. Use the Pythagorean Theorem to decide if the triangle is a right triangle. N Y Y Y N Y Find the missing side using the Pythagorean Theorem.
