Consider reflections of ΔJKL. What line of reflection maps point K to point K' at (–5, 2)? What line of reflection maps point L
telo118 [61]

Answer:When a point is reflected it must be reflected over a line

The transformation from K to K' is a reflection over the y-axis

The transformation from I to I' is a reflection over the line y= -x

From the complete question, the given parameters are:

c

       

   

(a) From K to K'

We have:

Notice that, only the x-coordinate of point K is negated to form point K'

This means that: the transformation from K to K' is:

Answer:

A. = 20 in²

B. =  45 ft²

C. = 29.5 ft²

D. = 36 ft²

E. = 28 ft²

Step-by-step explanation:

A. Formula = A = (h_b b)/2 = base 10 ft height_b= 4ft = 20 ft²

B. We have a rectagnle and a triangle:  Formula: A = lw

=  A = 30 ft² and now the triangle with the same formula as above: A = 15 ft²

30 ft²+15 ft² = 45 ft²

C. we have 2 rectagnle and a triangle: First the small recangle: A= lw = A = 1ft x 2ft = 2ft²

Second rectangle: 5 ft x 4 ft = 20 ft²

Right angeled triangle Formula: (ab)/2 = 3 ft x 5 ft = 7.5 ft²

Add it all together:  2ft²+20ft²+7.5ft² = 29.5 ft²

D. is a rectangle and a triangle: 8 ft x 3 ft = 24ft²

the triangle 8 ft x 2ft = 12 ft²; add 24 ft²+12 ft² = 36ft²

E. is a right-angled triangle (see fromula above) =  (14 ft x 4 ft)/2 = 28ft²
