Answer: 80°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. Since the two angles of a triangle measure 15° and 85°.
The measure for the third angle will be:
= 180° - (15° + 85°)
= 180° - 100°
= 80°
The third angle is 80°
The first sentence → x - 2y = -1
the second one → 3x - 2y = -3
multiply the first one by -1
you can get → -x + 2y = 1
plus two sentences together
you can get → 2x = -2
so you are able to know that x = -1
and y = 0

Answer:
80 minutes or 1 h 20 minutes
Step-by-step explanation:
15-13=2
2/0.025=80
So we can conclude that it takes 80 minutes till it reaches 13 feet.
