Choose 'A' for true or 'B' for false. 65. Tangent ratios of complementary angles are reciprocals. 66. The sine ratio can be greater than 1. 67. The cosine ratio is never greater than 1. 68. The tangent ratio involves the legs of a right triangle. 69. As acute angles get larger, the sine ratio gets larger. 70. The tangent ratio can be greater than 1. 71. The sine of an angle and the cosine of its complement are equal. 72. As acute angles get larger, the cosine ratio gets larger. 73. Trigonometric ratios can be found by using a table of trigonometric values or a calculator. 74. sin 72° = sin18° 75. cos 65° = sin 25° GSE Geometry A Week 14 Page 32 of 33
