Hi!
We can see the river is a straight line.
This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.
Therefore:

Combine like terms:

Subtract 21 from both sides:

Answer:
The student will have to save $404.2 minimum monthly
Step-by-step explanation:
Given that the total cost for the first year= $19,700
The grandparents paid half the amount = 1/2(19700)= $9850
The remaining balance to be paid is
19,700 - 9850=$9850
If an athlete paid $5000
The the remaining balance to be paid = 9850-5000=$4850
For the student to clear this amount in 12 months he must save
monthly 4850/12= $404.166
Hence the minimum amount to be saved per month is $404.2
