Answer:
m∠C = 35°
Step-by-step explanation:
Data
From the figure, it can be seen that a right triangle is formed where CA is the hypotenuse and CD is one of the legs.
From definition:
cos(C) = adjacent/hypotenuse
cos(C) = CD/CA
cos(C) = 23/28
m∠C = arccos(23/28)
m∠C = 35°
The answer is D
Following the point - slope form : y - y1 = m ( x - x1 )
Answer:
c:8
Step-by-step explanation:
10/25 = r/20
25r = 200
25 25
r = 8
We know:
397 total
53 fewer student tickets than adult tickets
Variables: A for adult tickets, S for student tickets
Known Equations:
a + s = 397
a = s + 53
Solving:
2s + 53 = 397 so 2s = 344 so s = 172
s + a = 397
172 + (172 + 53) = 397 so 172 + 225 = 397
Adult tickets sold: 225
Student tickets sold: 172
It would be 0.068 x $2029.20 which is 137.9856. Then you take away 137.9856 from $2029.20 which is equal to $1,891.2144
