Highly-Leveraged Standard1
G-SRT.C.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
Student Learning Targets:
Students will be able to:
 use the trigonometric functions to find the unknown sides of a right triangle.
 use the trigonometric inverses to find the unknown angles of a right triangle.
 find all of the unknown sides and angles of a right triangle.
 solve right triangles in applied problems using trigonometric ratios and the Pythagorean Theorem.

Highly-Leveraged Standards are the most essential for students to learn because they have endurance, leverage and essentiality.
This definition for highly-leveraged standards was adapted from the website of Millis Public Schools, K-12, in Massachusetts, USA.

Specifically for mathematics, the Highly-Leveraged Standards are the Major Content/Clusters as defined by the AZCCRS Grade
Level Focus documents. They should encompass a range of at least 65%-75% for Major Content/Clusters and a range of 25%-35%
for Supporting Cluster Instruction. See the Grade Level Focus documents at:
