Show that sin^2 20° + sin^2 40° + sin^2 80° = 3/2

(HINT: 40° = 60° – 20° and 80° = 60° + 20°​

Use circumcenter theorem to solve for the given values

Ineed big ! the cost of a school banquet is $25 plus $15 for each person attending. create a table, sketch the graph, and write an equation in slope-intercept and point-slope form that gives total cost as a function of the number of people attending. what is the cost for 77 people?
