Cosine means complementary sine, the sine of an angle and the cosine of the complementary angle are the same.
sin 75° = cos θ
cos (90° - 75°) = cos θ
cos 15° = cos θ
In general when we have
cos x = cos a
the solution is
x = ±a + 360°k, integer k
Here they just went with x=a, or
θ = 15°
Answer: C θ = 15°
Hi there,

Answer:
14x+6z
Step-by-step explanation:
distribute 2 into (4x-3z) and 3 into (2x+4z)
8x-6z+6x+12z
combine like terms
8x+6x=14x
12z-6z=6z
14x+6z
hope this helps
