We continued to solve for a missing angle and 2 missing sides of a right triangle. Alexa had to use the law of the angles of triangles to find the missing angle. She then used Trig Functions to find the missing sides. She is getting better about knowing which sides are the adjacent and opposite sides.

Alexa did not answer the call until 9:30, rather than 9.
Using a right triangle, Alexa was given an angle and a side. She had to use the fact that the sum of the angles of a triangle is 180 degrees to find the missing angle. She could then use her 2 acute angles and trig functions to find the missing sides of the triangle. We did not have much time, but will continue tomorrow.
Alexa and I looked at exercises from one of my old textbooks on solving right triangles. She and I worked through 10 problems that gave her either 2 sides of a triangle, and she had to find the measurement of an angle, or she was given one side length of a triangle, and one angle measurement, and had to find another side. This required her to determine the relationship between the angle and the sides, and then choose the correct trig function to relate that measurement. I also taught her how to find the inverse of the trig functions.
At the end of our session, I pulled up logic puzzles on my computer and went through some of those with her.

Alexa did not pick up the call for the first hour of our session, between 9-10.
I checked Alexa's corrections on Evaluating functions, which she did correctly. We then reviewed the Right Triangle Trigonometry Functions. I had her practice deciding which sides were adjacent and opposite to certain angles. We then worked out a problem that gave us the measures of two angles and a side length of a triangle, and asked us to find the other two sides and the third angle. We used the fact that 3 angles of a triangle add to 180 to find the third angle. Then we used Trig Functions to find the unknown sides.

Alexa and I were scheduled to begin at 9. She did not answer the call until 9:30.
Ayden and I worked on one more set of function tables and graphs. He is doing well with them. We then looked at tables of independent and dependent variables, and Ayden evaluated their relationships. He was able to write functions describing these relationships.
Alexa and I went over her homework for the last quarter. She needed corrections on exponential decay and growth, and their graphs. She also needed clarification about evaluating functions. I asked her to correct a few of them on her own.
