Atruck enters a stretch of road that drops 4 meters
in elevation for every 100 meters along the length of
the road. the road is at 1,300 meters elevation where
the truck entered, and the truck is traveling at
16 meters per second along the road. what is the
elevation of the road, in meters, at the point where
the truck passes t seconds after entering the road?

1300 - 0.64t Answer<

m = -4m/ 100m = -.04

1300 - .04 (16) (t)

Meters - .04 (Meters / sec.) (sec.)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Ibelieve the answer would be b.
