Draw line ac using a ruler. Taking a compass, place the point on one end of the line ac. Set the compass to 5cm, then draw an arc. Next, place the compass point on the other side of like ac. Set the compass to 6cm and draw an arc. The point of intersection between the two arcs it the point of your triangle. Now draw likes from this point of intersection to either side of ac.

A triangle has vertices at (1,10), (-5,2), and (7,2). What is its orthocenter. Show your work.
kondor19780726 [428]

Answer:

Question: What is the orthocenter of a triangle with the vertices (-1,2) (5,2) and (2,1)?

The coordinates of point A are (-1,2), point B are (5,2), and point C are (2,1).

The orthocent is the intersection of the three altitudes. An altitude goes from a vertex and is perpendicular to the line containing the opposite side.

In the coordinate plane the equations of the altitudes can be found and then a system of equations can be solved.

Altitude 1. From point C perpendicular to the line containing side AB.

Slope of line AB is 0 (horizontal line), a vertical line is perpendicular to a horizontal line. Thus, the equation of altitude 1 is  x=2 .

Altitude 2. From point B perpendicular to the line containing side AC.

Slope of line AC is  −13 , the slope of a line perpendicular to line AC is 3. The equation of altitude 2 is  y=3x−13  

Altitude 3. From point A perpendicular to the line containing side BC.

Slope of line BC is  13 , the slope of a line perpendicular to line BC is  −3 . The equation of altitude 3 is  y=−3x−1  

The orthocenter is the point where all three altitudes intersect.

x=2  

y=3x−13  

y=−3x−1  

Use substitution to solve the first two equations  y=3(2)−13=−7  

The orthocenter is the point  (2,−7)  

we did not need the third equation, but we can use it as a check, plug the coordinates into the third equation:

−7=−3(2)−1  

−7=−6−1  

−7=−7  it works.

The length of each of the legs of an isosceles triangle is 3ft less than twice the length of the base. The perimeter of the tria
Marrrta [24]

The base is 11 ft and the legs are both 19ft.

x+2x-36+2x-36=588

Addition Property of Equality

x+2x+2x=660

Combine Like Terms

5x=660

Division Property of Equality

x=132in

2(132)-36=228in

132in÷12=11ft

228in÷12=19ft
