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.
For the first one it’s h=6 and the second one is h=-3
X=12sin(60). X=10.3923...X=6rad3
