The supertanker and the iceberg are
headed straight toward each other. the
supertanker is traveling at a speed of 12
miles per hour, while the iceberg is
traveling at 0.5 miles per hour. if the two
are exactly 50 miles apart, in how many
hours will they hit?

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

The difference is 5,100m?
