Help on this I got this wrong
1 answer:
Check the picture below.
recall, AB = AC, and AR is an angle bisector to the vertex A, so A gets split into two equal angles, so those angles are twins.
now, the segment AR is part of triangle ABR and is also part of the triange ACR, however, is being shared by both, and therefore, is the same length on each triangle.
so you have a Side, in green, an Angle, from the twins, and another Side, being shared by both, Side Angle Side, SAS.

Answer:
To raise exactly $240, the charity needs to sell 20 snacks.
Step-by-step explanation:
Let
s = number of seats sold
y = number of snacks sold
Seats cost $24 each, then s seats cost $24s.
Snacks cost an additional $6 each, then y snacks cost $6y.
In total, s seats and y snacks cost $(24s+6y).
The charity needs to raise $240 to consider this event a success, so
If 5 seats are sold, then
To raise exactly $240, the charity needs to sell 20 snacks.
To solve this problem graphically, plot the graph of the line and find on this line point with s-coordinate 5. This is exactly point (5,20), so the charity needs to sell 20 snacks.
