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.
good scribepost because you putted alot of info that shows what the question means and how its meant to be but you could have put some alittle color if you want but great underlining the important math words anyway good scribe post
