Use a sim or difference identity and the given table for values of trig functions to find the exact value of cos(135+120).

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

the answer to this question is 3/19

step-by-step explanation:

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
