With these questions, the best approach is to draw a diagram to represent the question. Draw a right angle triangle with an angle of elevation 29 degrees (make sure to label the angle that meets the base and hypotenuse as 29 degrees).
From here, we say that the hypotenuse is the slide itself, which is 5.4 metres. Using basic trigonometric ratios, we can deduce that:
sin(29) = x/5.4
x = 5.4sin(29) which is approximately 2.62 metres.
The answer to this question is the last option: “The distance traveled in York Canal is 1/2 the distance traveled on Stover Lake” as 5 is 1/2 of 10
When you multiply or divide a whole number by a power of ten just add the zeros. 5 to the 100000 power is 500000. Five zeros. Hope this helps. Just a little trick and pattern I noticed which helps. :)
If you use FOIL to multiply these two brackets, it will lead you what is exactly written (xa+xb+ya+yb)
so it is correct
