For a project in his Geometry class, Hudson uses a mirror on the ground to measure the height of his school’s football goalpost. He walks a distance of 9.65 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. He then steps 3 meters to the other side of the mirror, until he can see the top of the goalpost clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.55 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
