Consider the equation cos(2.54t) = - 0.7 Find the smallest positive solution in radians and round your answento 4 decimal places

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
