Answer:
x= -8 BDC= 68
EXPLANATION:
They create a straight angle which is always equal to 180. this means you must add both equations and set them equal to 180.
23(x)-85
Substitute 12 for x
23(12)-85
276-85

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.
Step-by-step explanation:
Hey there!
The equation of a circle which passes through any point having centre (h,k) is;

In first blank ( x-_ ) keep "-2". In second blank (y - _ ) keep "4" and in last blank ( _ ) keep "36".

12. Both sides of the equation are equal and if 18 is half of 36 then 6×2 will give you the value of X
