(8x-10)°+(6x)°+(10x+10)°=360°
8x-10+6x+10x+10=360
8x+6x+10x-10+10=360
24x-10+10=360
24x=360
24x/24=360/24
x=15
Scalene because all three sides are different.
Answer: 0.61
Step-by-step explanation:
Perimeter of a triangle = all 3 sides added together
x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==
(x - h)² + (y - k)² = 25
(x - (-4))² + (y + (-6))² = 25
(x + 4)² + (y - 6)² = 25
(h, k) = (-4, 6)
The answer is B.
