The warm-up includes examples of what was covered last week. We worked on setting up ratios and finding unit prices. Today we looked at % mark up on the cost of an item, sales tax, and determining a final price.Lesson attached. The answers for homework are also in the lesson so students are expected to show their work and compare their answers. Come to class tomorrow with any questions you have about homework.

Today the students wrote a quiz at the beginning of class covering everything up to this point (primary trig ratios, solving for a missing angle, solving for a missing side). We reviewed homework from last week and then looked at examples of solving triangles where students are expected to find all three sides and all three angles. They should only have to use their primary trig ratios once, and then they should be able to find the rest using other skills like Pythagorean Theorem and Sum of Angles of a Triangle Theorem.Students were assigned #1-7 on their worksheet to 'solve' each triangle. They will not be able to complete #3 as they are missing information.

Yesterday students practiced labelling their triangle and finding all 3 primary trig ratios. Today we looked at how all 3 trig ratios lead to the same angle when we solve for the missing angle. Tonight for homework students are expected to choose the one primary trig ratio they will need to find theta, and then solve for the missing angle.All overdue assignments are due by Thursday at the latest!Lesson is attached.

Today we practiced parallel line theorems. Students were given examples to work on in class and other questions to work on for homework. The warm-up question we worked on is attached. If anyone was not here today to get the sheets they can do any of the practice questions on either side of their long sheet from last night.
