An aircraft is approaching the runway to land. the aircraft is ata height of h=313 meters from the runway. the angle of the elevation, a, from the top of air trafic control tower to the aircraft is 17°. if the height of the tower is 70 meters, abouy how far is the aircraft from the top of the tower?

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

answer4 to the second power is 16

and 4 to the third power is 64,

the correct option is b
