For this question, I am supposed to find the length of the red line(C). I can do this by making a right triangle with the red line as the hypotenuse. The legs would meet each other at 5,2. The vertical leg (A) would be 4 units long and the horizontal leg (B) would be 2 units long. I can use this information to first, find out the length of C² and then find the length of C.
A² + B² = C²
4 cm² + 2 cm² = C²
(4 cm x 4 cm)+( 2cm x 2cm) = C²
16 cm + 4cm = C²
20 cm = C²
√ 20 cm = √ C²
4.5 cm= C
The red line has a length of 4.5 centimeters.
