Manipulate Triangle ABC in the slide above to create a different size Triangle ABC. Take a screen shot of your Triangle ABC and upload it to the show your work section. Use your Triangle ABC to find QS.
Round to nearest tenth
Did you get the same length for QS as your group mates even though your Triangle ABC's were different sizes. Why is this the case?
Now go back to your Triangle ABC.
Find
Is your
ratio equal your group mates ratios?Now using your calculator type [tan] 25 into your calculator.
In the show your work area now lets solve for QS again but by using the trigonometric ratio rather than the actual corresponding sides of a triangle similar to Triangle QRS.
Height of the building to the nearest tenth of a foot =
Height of the wall to the nearest tenth of a foot =
