HW 9
Does anyone have any hints for #8 and #10?
for # 10, write out the 3 triangles made up by the one standing up. you will see some equal sides and some equal angles. play with angles adding to 180 and you should get there. sorry. equal sides since they touch.
Doing #8 and no clue!
Also would appreciate any hints for #9. Thanks.
