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°
7 X 4 = 28 if it’s hard for you just add 7, 4 times
Answer:
12.60
Step-by-step explanation:
give brainliest and 5 star and thank!
Supplementary angles add up to 180
180 - 118 = 62
so the answer is true.
In 15 days, I hope u get it correct, or wait till someone else verifies!
∆h= 235-205= 30
2per day
so in 30 cm
30/2= 15
