Answer:
(c) The two quantities are equal.
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement. In a right triangle, the acute angles are complementary, which means ...
sin(A) = cos(B)
The two quantities are equal.
Answer:
Step-by-step explanation:
Sin(A) = opposite / hypotenuse
opposite = 4
hypotenuse = 5
Sin(A) = 4/5 = 0.8
Cos(B) = adjacent / hypotenuse.
adjacent = 4
hypotenuse = 5
Cos(B) = 4/5 = 0.8
Believe it or not, this will always happen if you take Sin(A) and find that Cos(90 - A) are equal
Take a simpler case. Suppose you are working with a 30 60 90 triangle.
Cos(60) = Sin(90 - 60) = 1/2
