Using a pencil pair of compasses and ruler construct a right angled triangle with hypotenuse 9cm and shorter side 4cm. Measure the angle opposite 4cm to the nearest degree

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

i believe the answer is 323 ft
