Answer:
5.7m
Step-by-step explanation:
the easiest way to solve for a side is to draw the question in a diagram (i have done this below). As it is a right-angled triangle and we know 2 of the side, we can use the Pythagoras theorem:
sides a and b are the two shorter sides.
side c is the hypotenuse (longest side)
as shown in the picture below, because we know both sides c and b, we need to change the equation around:
replace these sides with their numbers:
(remember that 32 equals side a squared therefore we need to square root 32 to find the length of side a:
the question says to round to the nearest tenth meter:
Missing side = 5.7m
I hope this was helpful :-)
