Let's assume
shorter side as x
so, first side =2x
third side =x+19
now, we can find perimeter of triangle
perimeter of any triangle is
first side + shortest side + third side
so, we get
we are given perimeter=187
so, we can set it to 187
and then solve for x
so,
shortest length is x=42 feet
First side =2x=2*42=84feet
third side =x+19=42+19=61 feet
so, dimensions are
first side is 42 feet
second side is 84 feet
third side is 61 feet................Answer
Recall the following identities:
from which we get
Since
is in the fourth quadrant
we know that
should be positive, so when we take the square root here, we should take the positive root.
Now recall that
and since
is in the fourth quadrant, we expect
to be negative. So,
One final identity:
from which we get
