Select all of the given trigonometric equations that are true statements. sin(180°) = cos(0°) cos(74°) = sin(16°) sin(20°) = cos
(70°) sin(A°) = cos(90° - A°) sin(A°) = cos(180° - A°) cos(140°) = sin(40°)
1 answer:
Answer:
Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)
Step-by-step explanation:
This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

4 times because if you count 10, 20, 30, 40, so it has to be 4
Your answer would be 600. all u have to do is multiply the degree rotation to the radius.
hope this has helped.
No because they 90 to 200 is 110 but 200 to 325 is 125
110 obviously does not equal 125
