Chapter 6: Trigonometric Functions: Right Triangle Approach

Solving a Right Triangle Solve the right triangle.

Find the angle between$0^{\circ }\text{\hspace{0.17em}and\hspace{0.17em}\hspace{0.17em}}{360}^{\circ }$ that is coterminal with the given angle.

${400}^{\circ }$

Solving a Right Triangle Solve the right triangle.

Find the angle between$0^{\circ }\text{\hspace{0.17em}and\hspace{0.17em}\hspace{0.17em}}{360}^{\circ }$ that is coterminal with the given angle.

${375}^{\circ }$

Solving a Right Triangle Solve the right triangle.

Find the angle between$0^{\circ }\text{\hspace{0.17em}and\hspace{0.17em}\hspace{0.17em}}{360}^{\circ }$ that is coterminal with the given angle.

${780}^{\circ }$

Find the angle between$0^{\circ }\text{\hspace{0.17em}and\hspace{0.17em}\hspace{0.17em}}{360}^{\circ }$ that is coterminal with the given angle.

$-{100}^{\circ }$

Solving a Right Triangle Solve the right triangle.

Using a Ruler to Estimate Trigonometric Ratios Use a ruler to carefully measure the sides of the triangle, and then use your measurements to estimate the six trigonometric ratios of $\theta$.

Find the angle between$0^{\circ }\text{\hspace{0.17em}and\hspace{0.17em}\hspace{0.17em}}{360}^{\circ }$ that is coterminal with the given angle.

${1270}^{\circ }$
