Since he descended 12 meters, we subtract this from the overall height of Mount Ka'ala, so then we are only calculating how high ABOVE the sea level it is.
1232 - 12 = 1220
The height of Mount Ka'ala is therefore 1,220 meters.
To calculate how much a fifth of Mount Ka'ala is (since the ranger station is 2/5's up), we would divide this number by 5
1220 ÷ 5 = 244
Since ONE fifth of the height is 244 meters, TWO fifths would be double that amount.
244 x 2 = 488
488 meters.
The ranger station is 488m above sea level.
If there is supposed to be a root sign it’s C.
< x is 90 degrees because triangle ABC is isosceles and AD bisects < BAC.
Triangle BAD is right angled so < y = 90 - <ABD
<ABD = <ACD ( because triangle ABC is isosceles
So < ABD = 47 degrees
Finally y = 90 - 47 = 43 degrees answer
Answer:should be about 170
