Answer:
104 degrees
Step-by-step explanation:
71 degrees is one corner
Opposite corner is equal
Middle angle: 180-71-71 = 38
isosceles triangle bottom angle = 38 and 38
top angle = 180 - 38 - 38 = 104 degrees
Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
