Answer:
Step-by-step explanation:
<u>Angle alpha is 16° greater than the angle beta:</u>
<u>Angle gamma is 52° smaller than the beta:</u>
<u>Sum of angles is 180°, substitute α and β:</u>
- α + β + γ = 180°
- β + 16° + β + β - 52° = 180°
- 3β - 36° = 180°
- 3β = 216°
- β = 216°/3
- β = 72°
<u>Then</u>
- α = 72° + 16° = 88°
- γ = 72° - 52° = 20°

Answer:
The function describes the motorboat's distance from the shore
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change =
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore
