Mrs Chuong leaves home at 08:00 and drives at a speed of 50km/h. After 1/2 hour she reduces her speed to 40km/h and continues at this speed until 09:30. She stops from 09:30 until 10:00 and then returns home at a speed of 60km/h. Use the graph to find the approximate time at which she arrives home.​

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

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
