Answer:
she did not apply the Pythagorean theorem correctly
Step-by-step explanation:
It should be
the sum of the squares of smaller sides equals to the square of the longest side. So in this case it is a right triangle: 25+144=169
What are the options in the boxes?
Find what is common between 35 and 55....and that would be 5....so factor 5 out
35x + 55 =
5(7x + 11) <==
Answer:
Step-by-step explanation:
<u>Finding corresponding side lengths</u> :
<u>Trapezium ABCD</u>
- AB = √(-2)² + (-1)² = √5
- BC = √(-1)² + (2)² = √5
- CD = √(2)² + (2)² = 2√2
- DA = √(-1)² + (5)² = √26
<u>Trapezium EFGH</u>
- EF = √(2)² + (1)² = √5
- FG = √(1)² + (2)² = √5
- GH = √(-2)² + (2)² = 2√2
- HE = √(1)² + (5)² = √26
As the corresponding side lengths are equal, we can conclude that the trapezoids are congruent.
The answer is 0.225
