Answer:
C. 45 degree angle
Step-by-step explanation:
let AB be the height of the wall and CD be the height of boy
with BC as distance between them.
we have AE = AB-BE = 3.64-1.54 = 2.1m
and ED = BC = 2.1m
in triangle AED, we have
tanФ = P/B = 2.1/2.1
tanФ = 1
∴ Ф = 45°
Hence the sun is elevated at an angle of 45 °.

Answer:
The answer is: Each adult ticket is $7 and each student ticket is $9.
Step-by-step explanation:
Let a = the number of adult tickets. Let s = the number of student tickets.
For day 1:
14a + 1s = $107
Solve for s:
s = 107 - 14a
For day 2:
12a + 5s = $129
By substitution:
12a + 5(107 - 14a) = 129
12a + 535 - 70a = 129
-58a = 129 - 535
-58a = -406
a = -406 / -58 = $7 for adult tickets
Solve for s:
s = 107 - 14a
s = 107 - 14(7)
s = 107 - 98
s = $9 for student tickets
Proofs:
For day 1:
14a + 1s = $107
14(7) + 1(9) = 107
98 + 9 = 107
107 = 107
For day 2:
12a + 5s = $129
12(7) + 5(9) = 129
84 + 45 = 129
129 = 129
