Answer:
(see attachment)
To approximate the square root of 13:
Working from the top down...
Enter the number you are trying to approximate in the top box: 
Find the perfect squares directly below and above 13.
Perfect squares: 1, 4, 9, 16, 25, 36, ...
Therefore, the perfect squares below and above 13 are: 9 and 16
Enter these with square root signs in the next two boxes: 
and 
Carry out the operation and enter 
and 
in the next two boxes.
Enter the number you are trying to square root (13) in the top left box, the perfect square above it (16) in the box below, then the perfect square below it (9) in the two boxes to the right of these. Carry out the subtractions and place the numbers in the boxes to the right.
Now enter the number you are trying to square root (13) under the square root sign. Place the square root of the perfect square below it (3) in the box to the right. Copy the fraction from above (4/7). Finally, enter this mixed number into a calculator and round to the nearest hundredth.

It is 252. hope I helped!
Answer:
Probably 5
Step-by-step explanation:
This is an extremely confusing question. Whoever wrote it most likely had a typo.
The little box in the corner of the triangle means that is 90 degrees. if that is the case, this is a simple question:
Apply pythagorean theorem (a^2 + b^2 = c^2)
In this case:
3^2 + 4^2 = x^2
x^2 = 25
x=5.
HOWEVER: the two given angles are 60 degrees and 50 degrees.
Which does not work. It creates an impossible triangle.
Answer:
The correct answer is D: LL ( Leg-Leg Congruence)
Step-by-step explanation:
Theorem 4.6 Leg -Leg Congruence said that if the legs of one right triangles are congruent to the corresponding legs of another right right, then the triangles are congruent.
So in this case we can tell that both triangle are congruent by Leg-Leg Congruence due to the tick marks we have on both of the legs on the two triangles.
