Nooo please don’t put B. It’s A,C, and D
Answer:
d. 8°
Step-by-step explanation:
It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.
For this case we have that by definition, the standard way to write the equation of a line, is given by:

Where a, b and c are integers.
Given 
We can write it in the standard way:

and by the previous definition, the numbers a, b and c must be integers.
Thus, we multiply the equation by 2, on both sides so as not to alter the equality.


Thus, the equation of
, in its standard form is given by:

Answer:
Option B
Answer:
Y=-4/5x+3/5y
Step-by-step explanation: first get the gradient
3--1/-3-2
=4/-5
y-3/x+3=4/-5
-5y+15=4x+12
-5y=4x-3
y=4/-5x+3/5
Reverse the formula of pi x r^2 = area to find r, the radius.
Then, use r in the formula 2pi x r to calculate the circumference.
