Answer:
The x- coordinates are equal at -3.
Step-by-step explanation:
Hello :
the center of this cercle is : O( 0, 0)
calculate the slope m of the line : OA .. A (3,-4)
m= (yA - yO) / (xA- xO)
m = (-4-0)/(3-0)
m= -4/3
if : k the slope of the tangent : k×m = -1 (the tangent perpendiclar of : OA)
k× (-4/3) = -1
k = 3/4
an equation of this tangent is : y - (-4) = (3/4)(x-3)
B the answer is b because yiu do like add e square 27 +* 9 + x = 8 -/273/73
Angle 1 is also 54. 2 and 4 are verticals. 4 is 126
4x-1=18
4x=18+1
4x=19
x=19/4
