Answer:
Figure D
Step-by-step explanation:
we know that
If the scale factor of the dilation is 1/2, that means the dilation is a reduction
so
the answer is between the Figure C and Figure D
but
a rotation of 180° eliminate the Figure C
therefore
The answer is the Figure D
Answer:
QR ≈ 16.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
57 QR = 926.9 ( divide both sides by 57 )
QR ≈ 16.3 ( to the nearest tenth )
Step-by-step explanation:
x= 10 sin 60° = 10×½√3 = 5√3
y= 10 cos 60° = 10×½ = 5
<span>8n-3=(-5)
Add 3 to both sides
8n=-2
Divide 8 on both sides
Final Answer: n=-2/8 or -1/4 or -0.25 *All answers are equivalent to each other.</span>
