Answer:
1.5 hours = 1 hour 30 mins
Step-by-step explanation:
3/4 = 0.75
0.75 x 2 = 1.5
Christy dove to the depth of 12 feet below the surface = -12 feet
(Below sea level means to be below zero, which are negative numbers)
Christy dove 12 feet back up to the surface= +12 feet
( When we come back up to the surface, the distance is taken always positive)
Therefore, we have to find the overall change,
Overall change = -12 feet + 12 feet
= -12 feet + 12 feet
= 0 ft.
Therefore, overall change is 0 ft.
The answer is 29.
All angles in a triangle add up to 180. If its a right triangle, you know one of the angles is 90, and it gives you that one of the angles is 61. All you have to do is subtract to find what the last angle is.
180 - 90 - 61 = 29
