Solving Right Triangles

Essential Question – What does it mean to solve a right triangle?

Solving a right triangle To solve a right triangle: – find the measure of all its missing parts (should be 3 sides and 3 angles).

Solving a Right Triangle Label sides Use SOHCAHTOA Solve for missing side(s) Solve for missing angle(s) You might need to do several problems in one to finish!

Example Solve the Δ A B C __ m  A=sin -1.96m  A=74 o m  B=90-74=16 o

Ex:solve the Δ (round to the nearest tenth) __ A B C =c =c 2 164=c =c m  A= tan m  A=51.3 o m  B= =38.7 o

Example S RT __ r s o r=5.1 m  S= m  S=70 o

Example solve the triangle 15.7mi 59mi x __
