3=21/(x+5)
Cross multiply
3(x+5)=21
Divide 3
X+5 = 7
Subtract 5
X= 2
If you rotate, translate, or reflect a figure, the afterimage will be congruent to the original.
But if you dilate the figure, you are changing the dimensions and the length of its sides. However, angle measures are preserved and therefore that makes the figure and its afterimage similar.
Therefore C.) produces a similar but not congruent figure because there is the dilation in it.
Answer:
x = 200
Step-by-step explanation:
plug in y
1/5x - 2/3(15) = 30
multiply
1/5x - 10 = 30
get x by itself
1/5x = 40
x = 200
Step-by-step explanation:
AC²=AB²+BC²
=(7)²+(13)²
=49+169= 218
AC=√218
= 14.7ft
therefore the original height of the tree
=7+14.7
=21.7ft
