### Trigonometry for real!

Lesson Objectives:

To be able to apply trigonometry in real life

Can we use trigonometry?

O = Tan angle x A

= Tan 40 x 6

= 5.03m

?

H

O

T A

O

40o

6m

A

How can we measure the angle?

How can we measure the length?

Tape measure ?

Trundle Wheel?

What data will you be recording?Design a data collection table to use next lessonYou need to calculate the height of:
• The Gym
• The Hall
• The Maths block
• The Canteen
• The Science block
• The height of the alarm on the main building
Discussion Points
• How close were the estimations you made?
