If 180°<α<270°, cos ⁡α= −8/17, 270°<β<360°, and sin β= −4/5, what is sin⁡(α+β)?

Step-by-step explanation:

Let determine the angles behind each trigonometric expression:

Given that , the value of is:

Given that , the value of is:

The sine function of the sum of angles can be determined by the following identity:

If and , then:

hey i’m new i won’t be answering any questions now bye peeps see you next time

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
