*CHECK THAT YOU DID ALL 4 STEPS!!!!1. Trigonometry is math studying triangles and the angles and sides of a triangle.

2. Euclid and Archimedes looked at chords of angles and created formulas. Islamic mathematicians used trigonometry for spherical geometry. Used for astronomy.

3. Architecture could use trigonometry because they deal with triangles as roofs and walls of houses and stuff like that.

4. Light pole- 7ft from the pole and the angle was 60 degrees. My eyes are 59 inches from the ground. This means that tan(60)=x/7 ----->the light pole is 12.12 feet tall.
Tree- We were 12 ft from the tree and the angle was 7 degrees. And it was 60 inches to our eyes from the ground. This means you would use tan(7)=x/12 -----------> the tree is 32.97 feet tall.
