Answer:
<em>Answer: SSS</em>
Step-by-step explanation:
<u>Triangle congruence</u>
We need to find out if triangles ABC and DCB are congruent.
The image shows one tick mark on sides AC and BD, thus they are congruent.
Two tick marks are shown on sides AB and CD, thus they are congruent.
Finally, both triangles share the side BC.
Being all three sides congruent, the triangles are congruent by the SSS (side-side-side) congruence theorem.
Answer: SSS
ANSWER
Emma is 44" tall
EXPLANATION
We have that David cast a shadow 42 inches long and he is 66 inches tall.
At that same place and time, Emma cast a shadow of 28 inches.
Since they are at the same spot and time, we can conclude that the ratio of their height to shadow must be the same.
Let Emma's height be x.
The ratio of David's shadow to height is:
42 : 66 or 42 / 66
For Emma, it is:
28 : x or 28 / x
That means that:

So, Emma is 44" tall.
Answer:
14.1 to the nearest tenth.
Step-by-step explanation:
x^2 = PT * WT as T is a tangent to the circle.
x^2 = (10 + 10)*10 = 200
x = √200
= 14.1.
Y = -7(over)-3. in fraction form.
Okay this should be simple...I remeber learning about this in class I just hope I did it right.
Add 27i to both sides
x * 3 - 27i + 27i = 0 + 27i
Then simplify
The form x * 3 = 27i
Divide both sides by 3
x * 3 27i
____ = ____
3 3
And now simplify to get your final answer
x = 9i
