The angle addition postulate is sometimes described as "the whole is equal to the sum of its parts." Explain how this descriptio
n applies to the angle addition postulate.
1 answer:
To explain this clearly, refer to the figure attached.
Angle addition, from the name itself, is the sum of the smaller angles to make up the bigger angle. In that case, the yellow angle plus the green angle, equals the maroon angle. As long as they have the same vertex (vertex O), you can add up angles that are side by side to obtain the value of the total angle. That is what the phrase <span>"the whole is equal to the sum of its parts" means.</span>

Answer: Option D
D. 880 = 45d + 70; 18 days
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call d the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
The answer is the option D
