Answer:
BC = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and exact value
sin30° = 
sin30° =
=
=
=
( cross- multiply )
2x = 12 ( divide both sides by 2 )
x = 6
That is BC = 6
Answer:
so the answer would points on al ine you got to make sure you look at the 5
Consider this option:
1.the equation of the circle using its centre and point (0;-4) is:
x²+y²=4.
2. to substitute given point (23;2) into the equation of the circle:
23²+2²≠4
answer: this point does not belongs to the circle.
I’m 98% sure it’s 7.275*10^0
