Step-by-step explanation:
Let θ be the angle of depression i.e the angle between the horizontal and the observer's line of sight.
tanθ= (Height of the light house)/(Horizontal distance of ship from the base of light house)
∴tanθ=88/1532=0.0574
∴θ=tan−1(0.0574)=3.290(2dp)
It’s 39 -180 because they are completray
If x orignial price than 60/100*x=80/100*(x-40) and selling price =60/100*x=96
Answer:
The slope is 6/9.
Step-by-step explanation:
The equation used to calculate the slope from two points is:
(y2 - y1) ÷ (x2 - x1) =
It <u>doesn't matter</u> which x or y you choose to be first since <u>you'll get the same answer</u>. (For me, it's easier to go with the bigger number as the second x & y, so that's what I did.)
(-1 - -7) ÷ (4 - -5) = <u>6/9</u>
