Answer:

  (d)  a translation of 6 units down, a rotation, and then a reflection

Step-by-step explanation:

Dilation by any scale factor other than 1 will prevent the original being congruent with its image. The only answer choice with no dilation is the one shown above.

A 5-foot tall person standing with her back to the sun casts an 12-foot long shadow. To the nearest degree, what angle does the
swat32

Answer:

  • 23°

Explanation:

<u>1) Data:</u>

a) height of the person = opposite-leg to the angle the sun makes with the ground = 5 ft

b) length of the shadow = adjacent-leg to the angle the sun makes with the ground = 12 ft

c) angle, α = ?

<u>2) Solution</u>

  • tanα = opposite-leg / adjacent-leg

  • tanα = 5 ft / 12 5t = 5/12

  • α = arctan(5/12) = 22.6°

  • 22.6° rounded to the nearest degree is 23° ← answer

HELP PLEASE ASAP NFJANFJKOANf
Stells [14]

Answer:

Coordinates of X is (7/2,9/2)

Coordinates of C is (6,7)

Explanation:

x is the midpint of DB and AC

coordinates of X = ( (5+2)/2 ,(6+3)/2)

= (7/2,9/2)

Coordinates of X is (7/2,9/2)

Let (a,b) be the coordinates of C.

Then,

coordinates of x = ((a+1)/2, (b+2)/2)

(7/2,9/2) = ((a+1)/2, (b+2)/2)

Hence,

7/2=(a+1)/2

7=a+1

a = 6

9/2 =(b+2)/2

9 =b+2

b =7

Coordinates of C is (6,7)
