Answer:
The length of the sides are 9 units, 18 units and 11 units
Step-by-step explanation:
Let
x ----> one side of the triangle
y ----> the longest side of the triangle
z ----> the third side of the triangle
we know that
The perimeter of triangle is equal to
we have
so
----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A
solve for y
<em>Find the value of x</em>
--->
<em>Find the value of z</em>
---->
therefore
The length of the sides are 9 units, 18 units and 11 units
You have to have the same unit of measure. Here your units are "minutes" and "seconds". In order to compare the two, you must change to 240 seconds into minutes (dividing by 60 = 4 mins) OR change the 5 minutes into seconds (multiply by 60 to give you 300 seconds)
The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.
X = 29
61 + 90 = 151
180-151 = 29
