There's an island off the coast of Nova Scotia is said to have incredible treasure buried deep underground, and people have been searching for it for over 2 centuries. Based off an old map, 2 brothers started at a
reference point R and located an old tunnel 100 m North of R at point T. They then restart at point R and
turn 50° East of North (or N 50°E) and discover a shaft 84 m away at point S. What's the distance between
the tunnel and the shaft? Include a fully labelled diagram.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

2 1/2 feet
