5. three men were trying to pull a tree stump out of the
ground. the first man was pulling with a force of 100 n
to the north. the second man was pulling with a force of
75 n at an angle of 45 degrees north of east. the third
man was pulling at 75 n at an angle of 45 degrees north
of west. what resultant force is being applied to the tree
stump?
4.4

step-by-step explanation:

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
