Let ∠1, ∠2, ∠3, and ∠4 have the following relationships. ∠1 and ∠2 are right vertical angles. ∠3 is an acute angle adjacent to ∠1. ∠4 is an acute angle adjacent to both ∠3 and ∠2. what is the sum of the measure of ∠1, the measure of ∠2, the measure of ∠3, and the measure of ∠4?

Fred and gene are hang gliding. fred is 700 feet above the ground and descending at 15 ft/s. gene is decending as shown in the table. interpret the rates of change and initial values of the linear functions in terms of the situations they model. show all work. freds equation is f(x)=-15x+700. ( genes is the table attached)
