We know that and this is the only point when sin and cos are equal lengths. Because both
Now if the sin of 30° is a half that would mean that cos of 60° is also a half.
Hope this helps.

Answer:
d = 65°
w = 55°
Step-by-step explanation:
m∠DAC +∠m∠CAB = 60
m∠DAC + 35 = 60
m∠DAC = 25
m∠DAC + d = 90
25 + d = 90
d = 65°
m∠GAF + w + d = 180
60 + w + 65 = 180
w + 125 = 180
w = 55°
I'm pretty sure the answer is A. But you might want to look online to make sure.
The cost increases 2.5$ for every additional pair of shoes rented.
Cost of 1st pair is 2.5$, cost of 2nd pair is increased by 2.54 so 2nd pair is 5$, cost of 3rd pair is increased by 2.5$ so 3rd pair is 7.5$ and cost of 4th is also increasing by 2.5$ so cost is 10$ for 4th pair.
