Matilda is practicing her marching band routine on the football field. She starts at the center of the field, marches 80 feet south then 60 feet west, and stops.

What is the direct distance from the center of the field to where Matilda stopped marching?

100 feet

Step-by-step explanation:

pythagorean theorm

60^2+80^2= 10,000

Square root of 10,000= 100

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
