# Unit 12 Trigonometry Homework 1 Answers

Trigonometry is one of the most important topics in mathematics, and it can be a challenging one for students. Unit 12 of trigonometry is especially difficult, with its long and complicated calculations. As part of this unit, students typically have to complete a homework assignment, and the answers to this homework can be difficult to find. Here we will provide the answers to Unit 12 trigonometry homework 1.

## Question 1 The answer to the first question is 0.7068. To solve this question, students must first identify the right triangle, then use the sine function to calculate the ratio between the two sides. The triangle in this case is a 3-4-5 right triangle, so the sine of the angle opposite the 4 side is 0.7068.

## Question 2 The answer to the second question is 0.4226. This can be solved using the cosine function, which is the ratio between the adjacent side and the hypotenuse. In this case, the adjacent side is 3 and the hypotenuse is 5, so the cosine of the angle opposite the 3 side is 0.4226.

## Question 3 The answer to the third question is 0.5. To work out this answer, students must use the tangent function, which is the ratio between the opposite side and the adjacent side. In this case, the opposite side is 4 and the adjacent side is 3, so the tangent of the angle opposite the 4 side is 0.5.

## Question 4 The answer to the fourth question is 60 degrees. This can be solved by using the inverse trigonometric functions. In this case, the sine of 0.7068 is 60 degrees, so the angle opposite the 4 side is 60 degrees.
