Answer:
(4,8)
Step-by-step explanation:
6x-4y=-8
11x+4y=76 eliminate y
6x+11y=-8+76
17 x=68
x=68/17=4
substitute x :
6x-4y=-8
6(4)-4y=-8
-4y=-8-24
y=-32/-4
y=8
Step-by-step explanation:
AB + BC = AC
50° + BC = 180°
BC = 180° - 50°
BC = 130°
AB = 50°
BC = 130°
AC = 180°
The equation of a circle is (x - a)² + (y - b)² = r², where the coordinates of the center(C) are C(a,b) and "r" the radius. Here, C(4,2) and if you need, r=3.

Answer:
33.29
Step-by-step explanation:
A=πr^2
A=π2^2=12.57
12.57/2=6.29
7-4=3
3x2=6
6/2=3
4x6=24
6.29+3+24=33.29
