Draw or Cut two similar squares with sides
units long.
Draw or cut four pairs of similar right triangles with side lengths as indicated in the diagram.
Now arrange the similar triangles at the corners of the squares such that the sides
of one similar triangle plus the side
of a second similar triangle coincides with the length of the square.
We do another arrangement of the similar triangles. This time arrange another 4 similar triangles in the opposite corners, such that each pair forms a square.
Now comparing the two different arrangements we got two different areas that are equal.
The area of the uncovered squares in the first arrangement is 
The area of the two uncovered squares in the second arrangement is 
Equating the two areas gives the Pythagoras Theorem

Note that
is the hypotenuse,
and
are two shorter sides of the similar right triangles.
34 × 1.22 - 0.89
= 41.48-0.89
= 40.59
Final answer =40.59
7 tenths is 0.7. The fraction form is 7/10, since the digit of 7 is in the tenths place.
I hope this helps, please Brainliest me, and have a great day! :D
C. 1/root2
Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.
Answer:
A.
1. 5cm
2. 10cm
3. 20cm
4. 40 cm
Step-by-step explanation:
I think you need to double the area of the scaled factor.
